the object is first created.

Now, we can schedule snapshots on pools from the CephBlockPool CR when
the pool is mirrored.
It can be enabled like this:
```
mirroring:
enabled: true
mode: pool
snapshotSchedules:
- interval: 24h # daily snapshots
startTime: 14:00:00-05:00
```
Multiple schedules are supported since snapshotSchedules is a list.

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.

The pool subdomains were being validated based on the names of the

The CRUSH map does not allow duplicate values (nor keys) for the
labels. That means that if the currently hardcoded label value
`default` occurs anywhere else in the tree (for example, because
some of the topology labels provided by the cloud provider use it),
the cluster cannot sucessfully spawn.
By giving the user control over the label value used for the root
CRUSH map label, it is possible to adapt the cluster to this
situation.
To be able to actually use the `default` value, the root=default
node which is created by default by ceph itself has to be removed;
since that node is accompanied by a replicated crush rule, we have
to remove that rule, too.
The integration tests are modified to sometimes use the custom
crushRoot (based on an arbitrary criterium) to get coverage across
the various suites. Separate tests could be added, but were not
deemed necessary at this point.
Fixes#4993.

Rook is now capable of configuring mirroring between sites. The
implementation works at different levels:
* CephBlockPool: which introduces a new `mirroring` configuration as well
as `statusCheck`. When turned on, Rook will enable mirroring on the
pool. It will also create a bootstrap peer token and store it in a
Kubernetes Secret. The name of that Secret can be found in the Status
field of the CephBlockPool CRD. This token can be fetched and used by
other clusters to configure the site as a peer. Mirroring can be
configured either at the pool or the image level.
* CephRBDMirror: which introduces a new `peers` configuration allowing
Rook to connect to peers by passing a Secret name. The administrator will
create a Kubernetes Secret with 2 keys: 'token' for the bootstrap peer
token and 'pool' for the name of pool. Once detected the rbd-mirror
controller will go ahead and import the peer configuration.
Pool mirroring status example:
```

info:
rbdMirrorBootstrapPeerSecretName: pool-peer-token-test

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
become too complex.

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
readable and have better functions/methods/tests separations.

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.

The pools had some legacy structs that translated between the
ceph.v1 types used by the CRDs and the internal implementation
of the pools. This simplifies the pool implementation by removing
the intermediate model and leaving us only with the ceph v1
pool types and no unnecessary translation.

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

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.

The CephCluster CR contains settings that are needed by other
CRs to configure the Ceph daemons. When the CephCluster CR
is updated, the updates will now be passed on to each of the
CR controllers to ensure the daemons are updated properly

When calling the controllers from another controller,
we ensure that only a single goroutine is handling
CRs at any given time to prevent contention across
multiple CRs of the same type.
