The operator settings loaded from the configmap have proven
inefficient for load time and frequently checking the configmap.
To avoid this ineffenciency, the configmap is only loaded once
each time it is created or updated. The values in the configmap
are applied as environment variables, which then are very efficient
to query throughout the various controllers, without needing
to be concerned about loading the configmap again.

Implement an allow list mechanism that disables potentially unsafe OBC
fields by default. OBC fields beyond `maxObjects` and `maxSize` don't
neatly fit into the OBC framework as it was originally envisioned and
implemented.
Some of the newly added configs could allow users to cause confusion for
themselves. Others might allow users to hijack others buckets. Some
might allow bricking the entire S3 store.
Out of an abundance of safety, allow-list the known-safe options by
default, and require administrators to enable potentially troublesome
options via the new operator-level config
`ROOK_OBC_ALLOW_ADDITIONAL_CONFIG_FIELDS`.

Previously, the struct maintaining the list of cluster was still
initialized with a cluster item. Then the monitoring check will see that
the cluster is part of the struct already and thus won't run the
monitoring go routine again.
Now each time we cancel the context, we also remove the cluster item
from the map so that when the controller runs again, the monitoring
struct is re-populated and the go routine runs and statuses are updated.

The built-in pools device_health_metrics and .nfs created by ceph
need to be configured for replicas, failure domain, etc.
To support this, we allow the pool to be created as a CR.
Since K8s does not support underscores in the resource names
the operator must translate this special pool name into
the name expected by ceph.
This also sets the basis for allowing filesystem data
pools to specify the desired pool name instead of requiring
a generated name.

The cluster CR can be forcefully deleted and cleanup the
cluster resources if the yes-really-destroy-data policy

treat the cluster CR as not existing and allow the finalizers

deletion.

This commit is a large refactor on how the operator starts, stops and
how it starts various sub-components such as the ceph-csi driver. It
also refines the way we cancel orchestrations. We don't use breakpoints
anymore but send our self a SIGUP to reload our controller runtime
manager.
The reload will happen under different circonstances like:
* a new adminission controller secret is created/deleted/changed
* a CephCluster CR is edited
As mentioned earlier, the csi driver now has its own controller, just
like flex. It reacts to change in the operator config map for particular
ROOK_CSI_ fields.
A second new controller for the operator's general config has been
created, it manages:
* the logging level
* the ceph CLI command timeout
* the discovery daemon
The operator reacts much more rapidly to cancellation events by stopping
the manager's context and reloading it.

If the reconcile is cancelled due to a CR update, we want to retry the next
reconcile immediately rather than wait for the exponential backoff timeout
if the reconcile was already failing. The wait can easily be minutes
if the reconcile was in this state, which makes it appear the operator
is ignoring the request to start a new reconcile.
Signed-off-by: Travis Nielsen <tnielsen@redhat.com>
We have been having many issues with external mode with Ceph version
mismatching. The operator would have a Ceph version different than the
external cluster. The `radosgw-admin` was used to interact with S3
users, even a small version delta would cause the command to coredump.
After checking with the rgw core team it appears Rook was misusing the
CLI and the admin ops API should be used instead.
So this patch is the first introduction of go-ceph in Rook to consume
the rgw admin ops API instead of the `radosgw-admin` CLI, **only** for
user management in this initial commit.
Later we can do more such as bucket operation, zone management etc.

If the ceph cli outputs an error with "error calling conf_read_file"
this means that the operator has not written its ceph configuration

After the operator restarts, the controllers will not all be able
to reconcile until the ceph config has been generated by the reconcile
of the CephCluster controller. The message printed to the operator log
is frequently seen as an error condition even though it is a normal
condition where we requeue the reconcile until the config is available.

We can now prioritize orchestrations on certain event. Today only two
events will cancel on-going orchestrations (if any):
* request for cluster deletion
* request for cluster upgrade
If one of the two are caught by the watcher we will cancel the on-going
orchestration.
For that we implemented a simple approach based on check points, where
we will check for a cancellation request in certain part of the
orchestration. Mainly before each mons/mgr/osds orchestration loops.
This solution is not perfect, but we are waiting for the
controller-runtime to release its 0.7 version which will embed context
support. With that we will be able to cancel reconciles more precisely
and rapidly.

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`.

So the watcher is outside of the main controller reconciliation loop of

* won't block anything from the main CephCluster controller loop
* fast than waiting for CephCluster loop to completion
