The flex driver does not need to be started if
only the CSI drivers are going to be used. Therefore,
we allow the admin to stop launching the rook flex
agent with the setting ROOK_ENABLE_FLEX_DRIVER in
operator.yaml

The version of the csi driver to be installed that is officially
supported is the default baked into rook. If a different version
needs to be specified, it is officially unsupported. Therefore,
we leave the csi driver version settings unspecified in operator.yaml
so we can officially support the defaults.

CSI is now the preferred storage driver for Rook.
By default both the CSI and flex drivers will be started
by the operator. In a future release the flex driver
will be deprecated, but for now is still supported.
The drivers can be disabled with an environment
variable in the operator deployment in operator.yaml.
If users are only using one driver or the other there is
no need to enable both drivers.

In order for the osd service account to reference the
cephcluster CR in the owner references, OpenShift requires
access to the CephCluster CRD. This adds the minimal changes
needed to appease OpenShift.

Now we collect logs for all pods and all their init and main
containers during the integration tests. No longer will we be
missing logs from the integration tests as long as the pods
are available when they are collected at the end of the test.
The pod descriptions are also written to a log file instead
of being included inline with the test output.

(cherry picked from commit 6e0bc338f90b3f36a89cf37b542ff4ff873b70bd)
The Ceph-CSI provisioners can hit a resource limit that is configured by
the container runtime (CRI-O restrict the number of processes/threads in
a container to 1024 by default). When there are spikes in the
provisioning, it is possible that the provisioners or helper executables
are not able to start new child processes, causing delays in the volume
creation or deletion.
A new --pidlimit command flag has been introduced with ceph/ceph-csi#517
and can be used to prevent the resource restrictions. This makes it
possible for the provisioners to stay responsive during spikes in the
requests.
The PID limit is configured to 'max' (value -1), but this can be adapted
to a (large) static value if needed.

This design proposes that rook creates and manages PDBs for all ceph
daemons. OSDs need special treatment and a new heuristic, but simple
PDBs will suffice for other daemon types.

a helper flag indicating the exitence of an empty zone (empty = no
monitor pods) is computed when checking the health of the cluster in
order to determine if mons from overloaded zones have some new location
they can be scheduled. the computation of this flag did not check that
the empty zone contains valid nodes that pods can be scheduled on to.
this lead to a mon creation loop.

In order to cleanup all cluster resources in case of cluster deletion
all resources have an ownerreference to the cluster crd instance.
Because the name of the reference was incorrectly set to the name of the
namespace the cluster resources can unintentionally be deleted by the
kubernetes garbage collector after a kubernetes cluster anomaly.

The status messages on the CRs had much duplicated code
for logging an error if the status update failed.
Now any failures around the status update are logged
consistently within the updateClusterStatus method
so there is no need to return an error and duplicate
the error handling everywhere.

Because the manager is running under the 'ceph' user the cephfs
subvolume plugin can not create directories anymore. It fails with a
permission denied because of the usage of the 'ceph' user, root is need
here, hence the special startup line to go over this.
