Travis Nielsen 87e2b09453 ceph: clarify log message for Ceph upgrades
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.

Sébastien HanandRohan CJ 90cd8224f4 ceph: add ceph-crash controller
A new controller to bootstrap ceph-crash pod on Ceph nodes running Ceph
pods only.

This implementation is unfortunately a mix of 'hacks' to make the daemon
working correclty. The ceph-crash script faced different issues:

* it's not a daemon
* it does not have any key in cephx
* it runs ceph commands under the hood which need an admin key and a
ceph.conf

On upstream Ceph, ceph-crash needs to grow better, once that happens we
will improve our implementation.

This also enhances osd provisionConfig struct with DataPathMap

Pod volumes and volume mount needs DataPathMap to perform the right
actions on log and crash dir. Exposing DataPathMap makes that possible.

Obviously, this is exposing ceph crash reports on the host as
well as pushing them into the mgr.
Basically, if a daemon fails, it'll put its core dump into
/var/lib/ceph/crash, bindmounting this dir on the host, ensures that the
crashes don't get lost when the pod dies.

Example:

```

Blaine Gardner db7a6da09e ceph: do ceph:ceph chown in init containers
Following the Ceph OSD rework, my test environment regularly failed to
start OSDs, as they would start before the postStart lifecyle hook which
was chown'ing the log and data directories could finish. Pods failed to
start for an arbitrarily long time before starting successfully. This
was a manifestation of a race condition identified in Ceph monitors in
https://github.com/rook/rook/pull/3594#discussion_r312279176

Create a Ceph operator-level method to create an init container that
will chown the necessary directories for all Ceph daemons (any daemon
which runs as the ceph:ceph user-and-group). Also add this container to
expectations for Ceph pod templates in unit tests.

Sébastien Han 087d71106b ceph: add a new CR property to force upgrades
On rare occasion, the ceph checks might not be 100% correct and the user
might decide to force an upgrade anyway.
Correctly, if we are in an upgrade, we perform `ok-to-stop` check for
each daemon, if one of them fails, we retry and eventually fail.
They are corner-cases where users would like to force the upgrade anyway.

Enhance the new CR property: "skipUpgradeChecks: true".

Sébastien Han 9824bd2ff9 ceph: improve upgrade procedure
When a cluster is updated with a different image version, this triggers
a serialized restart of all the pods. Prior to this commit, no safety
check were performed and rook was hoping for the best outcome.

Now before doing restarting a daemon we check it can be restarted. Once
it's restarted we also check we can pursue with the rest of the
platform. For instance, with monitors we check that they are in quorum,
for OSD we check that PGs are clean and for MDS we make sure they are
 all active.

Sébastien Han d4c48bb293 ceph: expose /var/log/ceph to the host
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.

Sébastien Han eb3c424d57 Ceph messengers 2 support
This commit introduces the necessary changes to support the new
messenger feature coming with Ceph Nautilus (currently in development).

What changes? Now the monitor listens on two port:

* old 6789 for messenger v1, which will help us support older client
(e,g: krbd)
* new 3300 for messengers v2, which brings new improvement in the
messaging layer. This new transport layer brings numerous advantages
such as encryption improvement, speed improvement, pluggable nature to
support different network stack than TCP and many more.

We still have one Service IP, however it has 2 ports, see:

```
NAME                      TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)             AGE
rook-ceph-mon-a           ClusterIP   10.106.217.160   <none>        3300/TCP,6789/TCP   4h
rook-ceph-mon-b           ClusterIP   10.99.36.175     <none>        3300/TCP,6789/TCP   4h
rook-ceph-mon-c           ClusterIP   10.108.220.74    <none>        3300/TCP,6789/TCP   4h
````

The `ceph.conf` has changed and we don't force the port when using an IP
address (public addr etc). Ceph, depending on its version will naturally
start the monitors on their right port, 6789.

A new --ceph-version-name CLI argument has been added to the Rook binary
so that when the pod starts it passes the ceph version name and the
configuration of the ceph.conf, as well as daemon startup flags, happen
properly.

Given that the Rook Operator remembers the port of all the monitors it
deployed (through Pod definition), this change is not an issue and will
maintain backward compatibility.

Note that to test this you must build rook with dev container image,
which contains the dev Nautilus version. So you should do something
like:

`make -j4 BASEIMAGE='ceph/daemon-base:latest-master' IMAGES='ceph' build`
