This removes the unnecessary check for taints on nodes in the
`GetNodeSchedulable()` function. This fixes that even though the user
has specified `tolerations` for, e.g., `NoSchedule` taints, that would
be ignored and the node(s) directly be "marked" as unschedulable.

when upgrading to a newer version of ceph that doesn't need the http
binding fix, this patch unwinds the configuration fix which may still be
present when upgrading from a cluster without the fix. if the
configuration fix remains then the dashboard and prometheus servers will
not be able to properly configure themselves.

The list of nodes to be queried for configuring OSDs
should include all of the K8s nodes before the placement
or other filters are applied. The operator was sometimes
missing configuring OSDs on nodes if the discover pod
hadn't finished running on a node. Now the osd prepare
job will be triggered on a node even if the discover pod
hasn't yet run there.

the http bind address fix in rook address an upstream issue in ceph in
which cherrypy break when binding to `::` when the host doesn't have an
ipv6 address. it fixes the issue by always binding prometheus and the
dashboard webservers to the pod address. by doing this, it prevents
using the kubectl port-forward technique, which some users would like.
a patch to cherrypy is upstream in ceph. this PR checks the ceph version
and selectively disables the fix so that both port-forward and the
normal service method works. this is the verison matrix:
FIX VER
--- ---
luminous merged (>= 12.2.12)
mimic merged (>= 13.2.6)
nautilus merged (>= 14.1.1)
when all the containers for these versions exists and sufficient time
passes the unreachable code guarded by the version checks in this patch
can be removed.

The ceph controller will delete and recreate the detec-version job, when
an already existing job is found. This helps avoid cluster creation from
getting hung up on waiting for an already existing/stale job to finish.

To enable multiple mgrs to run properly, we need to set the respective server_addr path with the mgr's name for the modules of each mgr.
When multiple mgrs are running, the modules( e.g. dashboard and Prometheus ) of each mgr need to bind its own server_addr when it is started. The way to get server_addr when ceph mgr starts the module is as follows: first, get the server_addr value by "mgr/<module-name>/<mgr-daemonid>/server_addr" path; and if this path does not exist, then get the server_addr value by" mgr/<module-name>/server_addr" path.
According to the original rook setting for server_addr, the modules of all mgrs take the same server_addr on ceph luminous and mimic, this produces a wrong result that only one mgr's modules can run properly ( the modules of other mgrs failed to start with the wrong server_addr).
This change is made to be compatible with ceph luminous, mimic, and nautilus. and Modify according to: the "HOST NAME AND PORT" description of http://docs.ceph.com/docs/master/mgr/dashboard/ .

This commits fixes the upgrade for cluster running on 0.9.x and thus
have monitors listening on 6790.
The only downside is that the new messengers 2 protocol can not be
enabled because Ceph expects monitors to listen on 6789.
In order to enable messengers 2 your monitors will have to failover so
they can pick up both 6789 and 3300 ports, then and only then messenger
2 can be enabled.

This commits allows the upgrade from Mimic to Nautilus to work by:
* removing the v2 brackets on the operator ceph config file generation,
we stick with v1 and can revert this back once we deprecate mimic there
is no rush since mons keep on listening to v1.
* enable messengers 2 when the cluster runs on Nautilus

The CephCluster CR contains settings that are needed by other
CRs to configure the Ceph daemons. When the CephCluster CR
is updated, the updates will now be passed on to each of the
CR controllers to ensure the daemons are updated properly
without requiring an operator restart.
When calling the controllers from another controller,
we ensure that only a single goroutine is handling
CRs at any given time to prevent contention across
multiple CRs of the same type.

As per https://github.com/ceph/ceph/pull/26856 Ceph tunes the value of
osd-memory-target when running the OSD process so there is no need to
enforce it.
We also set a safety factor to that value which has been calculated by
the Ceph eng/perf team. Without this factor, the OSD will get OOM killed
since it is consuming memory for other purposes too.

Because the deployment update-and-wait function waits for the deployment
to be ready, and that cannot happen due to the keyring not
having been updated yet. The keyring has its
owner set to the deployment so that no special keyring handling must
be done, but it must be created after the deployment UID is known.
Change the order of operations so that the existing deployment's UID can
be retrieved if it exists and the keyring created/updated before the
update-and-wait function is called.
This order-of-operations issue currently only applies to the mds. Other
daemons whose keyrings are owned by the replication controller do not
use the update-and-wait function.

We must expose the ceph version to the osd pod so that we can generate
the proper ceph configuration file. If we don't do this all the version
check will assume they run the opposite of the desired version and the
formatting of the `ceph.conf` will be wrong.

We now run all the daemon with a new option from Nautilus 14.2.1 which
allows us to tell to a daemon to not log on file. However, we can decide
to activate logging by editing the configuration flag 'log_to_file' via
the centralized config store like this for a particular daemon:
ceph config set mon.a log_to_file true
This is useful when a daemon keeps crashing and we want to collect log
files on the system.

It's quite convinient to expose /var/log/ceph so that we can decide to
activate logs locally on the machine and see what's going on.
This is only a placeholder when a daemon is stuck crashlooping and we
want to allow administrator to gather log files.
We still do not log on file but this can be activated via a config
option passed to the centralized config option store.
For some daemons, which typically do not store any data (rgw, rbd-mirror
and mds) we had to propagate dataDirHostPath from the cluster spec to
each creation call so that the bindmount can happen.

When instanciating an osd, we now pass clusterInfo which basically
represents a collection of information about a particular Ceph cluster. Rook uses information
// about the cluster to configure daemons to connect to the desired cluster.
From clusterInfo, we use the CephVersion which helps us putting
conditions for our code execution.
