If multiple removal jobs are fired in parallel, there is a risk of
losing data since we will forcefully remove the OSD. It's also simply
true if a single OSD is not safe to destroy, there is also a risk of
data loss.
So now, we check if the OSD is safe-to-destroy first and then proceed.
The code waits forever and retries every minute unless the
--force-osd-removal flag is passed.

Add ability to set device class for existing osd deployments,
based on its crush map device class.

A user with unbalanced system (e.g., some OSDs use a partition which
resides on a device along-side OS partition) may want to have a
fine-grained control on the overall load of specific OSD. While osd
weight affects write-load, primary-affinity affects read-load.
This patch allow user to define osd's primary-affinity (similar to
'DeviceClass' and 'InitialWeight'), which is sent to the osd (via mon)
as part of deployment sequence, using 'ceph osd primary-affinity' command.
Valid values are within the range [0.0, 1.0). If not set, default value
is 1.

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.

The Ceph version information is not needed to be passed
to the osd health checker since mimic support was dropped.

The ceph commands are now only written to the log in debug mode.
For commands that change the system state we now ensure that
a useful log entry is written. If all the details of the ceph
commands are needed, debug logging should still be enabled.

It's not 100% safe since before Nautilus osd safe-to-destroy command
didn't have any json output. So added a version check.

This reverts commit b7a564e929, reversing
changes made to 6996571b5c.
Reverting: Linking ceph noout to a node taint.
The taint is applied for reasons other than maintenance as well.
This also needs a way to respect user-set noout.
Need to revisit this with a better design.
