Checks the version of the configured ceph-csi image while starting the operator. The operator will fail if the image is not supported.
Added an additional parameter to operator to disable the check e.g. to test not yet supported csi images.

currently CSI templates have hardcoded kubelet
path which will be used for mounting PVC,this
will not work if kubelet is configured to use
different path, with this PR kubelet path
can be configured for CSI.

Add support for MachineDisruptionBudget controller and MachineLabel controller required for fencing
in OpenShift. This will ensure that machines are only fenced and OSDs are only stopped
when Ceph is in a healthy state.

grpc metrics is made option in rook
this can be disabled/enabled with ROOK_CSI_ENABLE_GRPC_METRCS
variable in operator.yaml
this will help admin who want to check the grpc metrics
of the ceph-csi plugins

Deployment behaves better when a node gets disconnected
from the rest of the cluster - new provisioner leader
is elected in ~15 seconds, while it may take up to
5 minutes for StatefulSet to start a new replica.
if kube version is 1.13.x deploy provisioner as statefulset.
if kube version is higher than 1.14+ deploy provisioner
as deployment.

Add a prefix to the csi drivername when ceph csi is deployed by rook.
This aims to prevent trivial conflict between csi instances when two
rook operators are deployed into the same cluster. By default the
prefix is the "<rook-namespace>." but can by customized on the cli
and via environment vars.

The discovery daemon is only necessary to be run when
OSDs are being created on raw devices and detect when
new devices are added to the cluster. If OSDs do not need
to be configured on devices, the discovery daemonset
has no need to be started.

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

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.

This change is meant to allow running operators locally on a developer machine.
The idea is to allow faster development cycles by reducing the time and complexity of building -> deploying -> debugging on cluster.
For operators that rely only on kubernetes API this works easily - see cockroachdb and minio examples in development-flow doc.
The change includes:
- rook.NewContext() - Refactored to remove repeating initialization code that was copy-pasted in most of the operators in order to create the clusterd.Context and the Clientsets. Also it detects the mode of working in-cluster vs external and sets up the external mode with standard user config (~/.kube/config) and a job executor.
- rook.GetOperatorImage() - Refactor this repeating code in many operators to detect the operator pod image. Also added a global flag --operator-image that developers can use to override this when running locally.
- rook.TerminateOnError() - Added a convenient function.
Create a cephconfig module in Ceph's daemon pkg source, and refactor the
config and keyring generation that exists in the mon package into the
new cephconfig package. The config/keyring generation code is used by
most all daemons and not just mon, so a new package is a more
appropriate place for this.
