If the ceph cli outputs an error with "error calling conf_read_file"
this means that the operator has not written its ceph configuration
file. Thus ceph cli commands will fail, so we can just ignore that since
the operator will soon write this file in its initialization sequence.

With Ceph Pacific, Rook can now deploy the cephfs-mirror daemon.
This initial commit covers the deployment of a single daemon only.
Multiple mirror daemons is currently untested.
Only a single mirror daemon is recommended.
The configuration of peers will come in a later PR since the mgr module
is still pending upstream: https://github.com/ceph/ceph/pull/39050
The same goes for integration tests, they will get added later once we
start testing on Pacific.

controllers and react upon the appropriate event.

Pools in stretch clusters will all use the same crush rule that
is generated by the operator when configuring the cluster for
stretch mode, with replica 4 and two replicas per failure domain.
Pools cannot create new crush rules, so we require that replica be
4 when the pools is created, EC is not allowed, and no new
crush rule will be created.

Due to #6492, preservePoolsOnDelete is not useful at all for CephFS;
after the filesystem is deleted, the leftover pools cannot be
reassocaited with a newly created filesystem without wiping all
metadata. The only way we can actually preserve data is keeping around
the entire filesystem.
This commit implements a `preserveFilesystemOnDelete` option which work
similar to the existing pool preservation option but instead keeps the
whole CephFS while taking it down and removing all MDSes.
This commit also changes all documentation to refer to this new option
with the intent of essentially deprecating `preservePoolsOnDelete`. IMO,
keeping around `preservePoolsOnDelete` is actively harmful because it
lulls users into thinking their data will be safe but, in reality,
recovering from this situation is highly complex and has large potential
for data loss.

To provide more context for executing commands in a ceph cluster,
the full clusterInfo is now passed to the ceph execution commands.
All information about the cluster will now be available throughout
all the areas of the operator. The namespace, ceph credentials,
mon endpoints, and other info is a core part of that cluster info.
Arguments passed through the controllers are also simplified for
mons, mgr, osds, and other daemons where the parameters had

We can now explicitly set any property on a given pool by using the new
Property field in the CephBlockPool Spec.
Also, this fixes the case where both `CephBlockPool` and `CephCluster`
are created at the same time. When Rook creates the pool, the cluster is
still being bootstrapped and the global option
`osd_pool_default_pg_autoscale_mode` has not bee set yet. So the pool
gets created but its `pg_autoscale_mode` property is set to `warn`
instead of `on`.

This is the final conversion to controller-runtime conversion. This time the
CephCluster CRD has been converted to use the controller-runtime
library.
The controller incorporates all the previous watchers too, so the Node
and hot-plug configmap are been watched too.
Only the operator setting configmap is not being watcher since it's not
related to the CephCluster CRD.
Not only the patch converts to controller-runtime but also tries to
re-organize the tree of the repo to actually make the code more

When updating the status on resources sometimes the update fails due to
the resource being an outdated version. This frequently occurs when
the same reconcile loop updates the status multiple times, or the finalizer
is added, or some other update to the resource. Upon the next reconcile
the error would generally go away since the status or finalizer didn't
need to be updated multiple times. But now the error is not expected
since the controller will retrieve the latest version of the resource
immediately before attempting to update it.

Now, the CephBlockPool CRD is managed with the controller-runtime.
So the watcher is outside of the main controller reconciliation loop of
CephCluster which brings numerous benefit such as:
* having its own reconciliation loop
* won't block anything from the main CephCluster controller loop
* fast than waiting for CephCluster loop to completion

We now always perform ok-to-stop change when the deployment is going to
be updated. This could be for various reasons like change in the spec or
a new Ceph image.
In any case, if Ceph resources are going to be restarted this must be
done carefully.
Also trimmed the isUpgrade variable, the upcoming commit will remove the
need of that variable.
Keeping isUpgrade from the controller code since we need it to detect
whether an orchestration upgrade should be triggered or not (based on
the ceph cluster status).
Also, we keep it on the child controllers so we don't go into an
orchestration phase if the cluster image hasn't changed. The child does
not need to be updated/go into its orchestration phase because the
cluster CR changed.

The operator kit had more utility originally when the operator
was creating and managing the TPRs and CRDs directly. Since
the CRDs are now created from a manifest and no longer by the
operators, the utility of operator kit is limited to the
controller watcher. Since we are moving to the controller runtime
we simplify the code to make the transition smoother. Now
there is only a simple WatchCR method that will need to be
replaced as we maek that transition.

We recently discovered a race condition which happens not to update the
child CRDs when CR image changes.
The race happens under the following sequence:
* orchestration onAdd() is called when the operator image restarts
or its image updated
* the orchestration then goes into processing mon/mgr/osd
* during this the cluster CR is updated so onUpdate() is called,
however, onAdd() is not done yet for child CRDs (mds, rgw)
* onUpdate() runs against the cluster CR and updates the cluster images
* by the time the child CRDs reached onUpdate() from their respective
ParentClusterChanged() methods, the image is already up to date
so we were exiting since our check for updating
these resources are based on the cluster image version
To fix this, we changed the comparison, but using isUpgrade instead and
slightly changed the way isUpgrade operates. So now, isUpgrade is true
even if the Ceph version is identical which allows us to verify whether
or not the image changed.

Add various upgrade tests so that the local cluster does not fail if
an upgrade is available on the external cluster.
Also, add better upgrades handling on update and on add. We now rely as
much as possible on a unique function that works both local and external
cluster 'detectAndValidateCephVersion()'. So the code will act the same
way wether a CR update is triggered or if the operator is restarted.
The health check now reports any topology changes on the external
cluster such as odd number of mons and low number. It will also detect
if the external cluster has been upgraded and will log that information,
helping the admin in his/her decision to trigger an image upgrade.
Finally, we prevent the creation of new CRs if the external cluster
version has a higher major number than the local one.

It's quite convinient to expose /var/log/ceph so that we can decide to
activate logs locally on the machine and see what's going on.
This is only a placeholder when a daemon is stuck crashlooping and we
want to allow administrator to gather log files.
We still do not log on file but this can be activated via a config
option passed to the centralized config option store.
For some daemons, which typically do not store any data (rgw, rbd-mirror

each creation call so that the bindmount can happen.
