The Ceph Mimic release introduced the monitor config store which allows
us to set configuration flag per daemon in a centralized fashion. Let's
use it for Mimic and newer and keep the CLI flag of daemon startup for
older versions.
The main benefit is that the config of a daemon can now be overridden.
Also, this commit refactors some code and add methods that are unit
tested.

Because of this, the mgr would be restarted if the operator image
change. This must not happen.
Added unit tests for cephMgrOrchestratorModuleEnvs() as well.

Some log messages indicate when the upgrade checks will be
performed. If the Ceph image hasn't changed, the upgrade checks
are skipped. The messages were confusing if running a Rook
upgrade.

Earlier, simultaneous drains could allow the drain detection to switch

The OSD needs to shut down quickly during upgrade, or other scenarios
where the OSD is being restarted. To facilitate this fast shutdown,
rook will run kill -9 on the osd process. The Ceph OSD is designed
to be safe even when killed like this. This allows the
ECONNREFUSED to be returned sooner, which will redirect the OSD
traffic to other OSDs and cause less downtime.

When the OSD is running on a PVC, the LV needs to be released immediately
after the OSD process exits. The cleanup was being skipped when the OSD
process exited and returning an error rather than allowing the
LV cleanup to proceed.

Since the lvm config might change again in the future and because the
filter in the conf is commented as an example, let's append our filter
instead of searching and replacing.

A recent PR #4172 added the ability for rook to create
the CSIDriver object on a kubernetes cluster. The change also
made it so that attachRequired value in the ceph CSI drivers
were set to false.
This leads to the entire attach skipping the AD controller
that deals with RWO attachment enforcement. Thus, if a
CephFS volume is marked RWO, 2 pods on different hosts can
end up mounting the same and consuming it at the same time.
Further for RBD, currently the image watchers are the only ones
that prevent a double mount of an image, other than the AD controller
enforcement of single attach for RWO RBD PVs. This has proven
not to be reliable in the face of MON failures, as the watcher
information is lost, and a second mount is allowed.
Thus, we need to bring back the attach requirement to leverage
kubernetes checks and balances for RWO volume type, and
prevent unwanted multi-attach use of the same.
This PR hence undoes some of the changes introduced by the
PR #4172, to bring the attacher side car back, and also declare
the attachRequired for both RBD and CephFS CSI plugins as true.
NOTE: Initially the attachRequired was set to false as this
improved attach times considerably on kubernetes, as the
entire phase was being avoided.

OSDs on PVCs need some anti-affinity or other node affinity in order
to attempt to spread the OSDs across nodes. The OSD anti-affinity
is only effective when the number of OSDs matches the node count,
but at least it is a start.

The app name was not being set in k8sutil's cmdreporter code, resulting
in jobs being labeled `app=` with no name. Change cmdreporter's `New`
method to validate the contents of the config struct and not the inputs
to the `New` method to help prevent an issue like this from creeping up
in the future.

During upgrade tests, Rook should verify that it can still run legacy
OSDs. This includes directory-based OSDs, filestore disk OSDs, and
bluestore disk OSDs installed without ceph-volume (i.e., before mimic
v13.2.2) can still be run after upgrade.
This necessitates running the upgrade test twice; once with filestore
and once with bluestore.
