Sébastien Han a6036074db core: more checkpoint for context cancelled
Some context canceled were missed and not reported correctly. We had
multiple reconcilers running in //. Since they all run in goroutine then
will continue to run until they timeout (if timeout is available,
    otherwise would run forever until the op is restarted).

Sébastien Han b89730d895 ceph: refactor operator initialization sequence
This commit is a large refactor on how the operator starts, stops and
how it starts various sub-components such as the ceph-csi driver. It
also refines the way we cancel orchestrations. We don't use breakpoints
anymore but send our self a SIGUP to reload our controller runtime
manager.
The reload will happen under different circonstances like:

* a new adminission controller secret is created/deleted/changed
* a CephCluster CR is edited

As mentioned earlier, the csi driver now has its own controller, just
like flex. It reacts to change in the operator config map for particular
ROOK_CSI_ fields.

A second new controller for the operator's general config has been
created, it manages:

* the logging level
* the ceph CLI command timeout
* the discovery daemon

The operator reacts much more rapidly to cancellation events by stopping
the manager's context and reloading it.

Blaine Gardner a95734160e ceph: create new osds on pvc before update existing
Add a new OSD provisioner status (reported by provisioner configmap)
that denotes that an OSD is preexisting and that OSD prepare does not
need to be run for the OSD. This only applies to OSDs on PVC currently
where existence of a deployment for the OSD indicates no further
provisioning needs to occur. New status is "preexisting".

Allow creating new OSDs on PVCs before updating existing ones by
allowing deferring OSDs during processing of OSD provisioning status
ConfigMaps. Deferral is identified by new "preexisting" status.

Add a unit test to ensure OSD on PVC provisioning occurs as expected
including deferring already-created OSDs to be updated after new PVCs
are created.

Travis Nielsen e74c7eaef8 ceph: refactor context and clusterInfo passed to the ceph commands
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.

Travis Nielsen a52948e7f7 ceph: continue orchestration even if osd status update fails
The communication between the operator and OSD prepare job
is done through updates to the configmap. If an update fails
to the configmap, we are anyway going to need to check the logs
for failure. So let's just log the error and make a best effort
to continue the orchestration. If the failure was temporary,
the next update to the status would succeed and likely continue
working as expected.

Description of your changes:
Fix security issues identified by TrailOfBits

Modifications in osd/status.go:
I opted by remove the offending variables because "c.checkNodesCompleted"
provides this variables always, so no need to initialize them.
var was not used, so i have replaced it by the blank identifier.

Modifications in machinelabel/add.go:
I have followed the same criteria used in other disruption packages,
and return the error if it is produced when we try to "watch" machines.

Travis Nielsen fbf3837f13 ceph: stop removing osds for any cephcluster CR update
Removing an OSD unintentionally can result in data loss,
which is to be prevented at all costs. Rook's functionality
to remove OSDs automatically when a node was removed from the
cluster CR has led on several occasions to users having OSDs
unintentionally removed from their cluster.

If the admin decides they really need to remove OSDs they should
do it as a one-time action that they intentionally run
rather than the operator attempting to manage the deletion
with desired state. The risk of misinterpreting the desired
state, even with a typo, is too great.

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:

- OSD prepare job is started for each PVC which activates the ceph-volume on each PVC
- Finally OSD is started on each of the PVC device.

Blaine Gardner a80082988d ceph: remove osds only when certain
Make the Ceph operator more cautious about when it decides to remove
nodes from the Rook-Ceph cluster which are acting as osd hosts.

When `useAllNodes` is set to `true` we assume that the user wants to
have the most hands-off experience. Node removals are allowed when a
node is delted from Kubernetes and when a node has its taints/affinities
modified by the user (but not by automatic k8s modification as much as
possible).

When `useAllnodes` is set to `false` the only time a node is removed is
if it is removed from the Ceph cluster definition.
