"/dev/sda", this is bad! We all know people should be using paths like
/dev/disk/by-id so we must support them.

Now, we can schedule snapshots on pools from the CephBlockPool CR when
the pool is mirrored.
It can be enabled like this:
```
mirroring:
enabled: true
mode: pool
snapshotSchedules:
- interval: 24h # daily snapshots
startTime: 14:00:00-05:00
```
Multiple schedules are supported since snapshotSchedules is a list.

When new pools are added to an already existing filesystem, we would
create them but not actually associate them to the filesystem. Ensure
that we do this.
Also, while we're here, we refactor the CreateFilesystem test: before,
we were not properly testing creating the filesystem from scratch
because we would return valid JSON for *every* ceph command. Change this
by making the first run return an error so that we get some better
coverage.
After this, we also add a check for the correctness of adding new pools
to the CreateFilesystem unittest.

Pools in stretch clusters will all use the same crush rule that
is generated by the operator when configuring the cluster for
stretch mode, with replica 4 and two replicas per failure domain.
Pools cannot create new crush rules, so we require that replica be
4 when the pools is created, EC is not allowed, and no new
crush rule will be created.

In clusters where only two datacenters (or similar failure domains)
are available, a different mon and osd approach is needed to deal
with the network partitions or some other reason for one of the failure
domains going down. The Ceph stretched cluster makes the mons aware
of the failure domains by configuring one as the arbiter in a third
zone, while keeping two replicas of the data in each of the data
zoens.

Golang maps order is not always guaranteed to be identical, which makes
the table driven test to fail. Because of the nature of the maps, it is
hard to predict the exact position of an element in the map. This
makes the table driven test flappy.
Reworked the unit test using a contains statement which achieves the
same validation.

When the Ceph cluster runs on PVC and the OSDs are encrypted we can
store LUKS's Key Encryption Key inside a Key Management System. Today,
Rook only supports HashiCorp Vault: https://www.vaultproject.io/
The CephCluster has now a new "security" field which will plug onto the
KMS. Here is an example:
security:
kms:
tokenSecretName: <name of the secret containing a Vault token, used
to authenticate>
connectionDetails: < a map of strings containing connection
information>

The CRUSH map does not allow duplicate values (nor keys) for the
labels. That means that if the currently hardcoded label value
`default` occurs anywhere else in the tree (for example, because
some of the topology labels provided by the cloud provider use it),
the cluster cannot sucessfully spawn.
By giving the user control over the label value used for the root
CRUSH map label, it is possible to adapt the cluster to this
situation.
To be able to actually use the `default` value, the root=default
node which is created by default by ceph itself has to be removed;
since that node is accompanied by a replicated crush rule, we have
to remove that rule, too.
The integration tests are modified to sometimes use the custom
crushRoot (based on an arbitrary criterium) to get coverage across
the various suites. Separate tests could be added, but were not
deemed necessary at this point.
Fixes#4993.

The pool spec has now a new property called "replicasPerFailureDomain"
which essentially represents the number of replicas to store in each
failure domain.
Assuming the failure domain is a datacenter (if the cluster is
stretched) then you will have 2 replicas per datacenter where each
replica ends up on a different host. This gives you a total of 4
replicas and for this, the "size" must be set to 4.

Rook is now capable of configuring mirroring between sites. The
implementation works at different levels:
* CephBlockPool: which introduces a new `mirroring` configuration as well
as `statusCheck`. When turned on, Rook will enable mirroring on the
pool. It will also create a bootstrap peer token and store it in a
Kubernetes Secret. The name of that Secret can be found in the Status
field of the CephBlockPool CRD. This token can be fetched and used by
other clusters to configure the site as a peer. Mirroring can be
configured either at the pool or the image level.
* CephRBDMirror: which introduces a new `peers` configuration allowing
Rook to connect to peers by passing a Secret name. The administrator will
create a Kubernetes Secret with 2 keys: 'token' for the bootstrap peer
token and 'pool' for the name of pool. Once detected the rbd-mirror
controller will go ahead and import the peer configuration.
Pool mirroring status example:
```

Some parameter like bluestore_min_alloc_size, bluestore_min_alloc_size_hdd need to be set during the bootstrap of the
ceph cluster in order to have bluestore created accordingly.
To do so rook users rely on the rook-config-override configmap.
Sadly the rook-ceph-osd-prepare job does not take in account this configmap to generate its ceph config.

a job can be run that will remove the OSD deployment
and purge the OSD from ceph. If the OSD is still up,
the purge will be rejected.
To purge multiple OSDs at the same time, the OSD IDs can be
specified as a comma-separated list.

Trying to execute a binary from the host within the container can result
in mismatched libraries. The host version is compiled with paths of
libraries on the host where the libs inside the container can differ.
Because the path is known and we only need to make sure whether the bin
exists or not then simply doing a lookup when we fallback on /rootfs is
sufficient.

callCephVolume() was using our exec interface with CombinedOutput which
means return both stdout and stderr. This is fine when preparing OSDs
since we read back the stdout and also want any errors if any (stderr).
However when listing OSD we only want the output since ceph-volume tends
to mix stdout and stderr in the output and does not always silence the
warning types/harmless errors. If the listing has a problem we report it
by printing the ceph-volume log file.

Based on the feature of metadata PVC for OSD: #4818, add the wal device.
For this, you need to create a new volumeClaimTemplates, its name must be "wal", if "wal" is
set, "metadata" device will refers specially for block.db device, and "wal" refers for block.wal
device in BlueStore.
A template will look like this:
```
volumeClaimTemplates:
- metadata:
name: data
spec:
resources:
requests:
storage: 10Gi
# IMPORTANT: Change the storage class depending on your environment (e.g. local-storage, gp2)
storageClassName: gp2
volumeMode: Block
accessModes:
- ReadWriteOnce
- metadata:
name: metadata
spec:
resources:
requests:
storage: 6Gi
# IMPORTANT: Change the storage class depending on your environment (e.g. local-storage, io1)
storageClassName: io1
volumeMode: Block
accessModes:
- ReadWriteOnce
- metadata:
name: wal
spec:
resources:
requests:
storage: 6Gi
# IMPORTANT: Change the storage class depending on your environment (e.g. local-storage, io1)
storageClassName: io1
volumeMode: Block
accessModes:

running ceph-volume activate.
