On rancher OS, the lvm binary is in a different location and cannot be
accessed via the root namespace. So we now also check directly from
/rootfs. When using nsenter, itbreaks out of container's mount
namespace and executes an lvm command.

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.

Older versions of lvm do not implement "--help" but "help" only where
new versions support both so let's use "help" so the check works for all
the versions.

Now the metadata pvc will also be encrypted if the storageClassDeviceSet
has the "encrypted" flag turned on.
Signed-off-by: Sébastien Han <seb@redhat.com>
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:

```
We now map block, block.db and block.wal directly inside the container instead of
running ceph-volume activate.

We can now encrypted OSD device that were provisioned via a storage
class using the PV interface.
The encryption works at the storageClassDeviceSets level, which means we
can have encrypted and non-encrypted sets.
Using the new key `encrypted` we can turn it on.

following below steps:
1. open files
2. defer file.close()
3. write
4.file.close()

File permissions need to be reduced to the minimum to avoid config

required to access the files, min privileges are set just as
another layer of security. This fixes gosec error G306.

This commit fixes where there are areas in which files and directories are
written and created with statically defined permissions. Many of these

To ensure a file handle is closed, we defer the close command
so it is guaranteed to run when the method returns. The closing
of the file handle is not going to fail in our usage since we aren't
using the SetDeadline on the files that would cancel a request
and return an error.

Now, we can not only cleanup monitor data, logs and crashes but the
disks too. As part of the cleanupPolicy CR spec, we have a new setting
called sanitizeDisk which holds more details:
* method: indicates if the entire disk should be sanitized or simply ceph's metadata.
Possible choices are 'complete' or 'quick' (default)
* dataSource: indicate where to get random bytes from to write on the disk.
Possible choices are 'zero' (default) or 'random'
Using random sources will consume entropy from the system and will take much more time then the zero source
* iteration: overwrite N times instead of the default (1). Takes an integer value

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 operator should only connect to ceph with a single set of creds.
In a converged cluster this will be the admin creds and in an external

implemented with a separate set of creds. To simplify the code these
are now merged to a single set.

We can now explicitly set any property on a given pool by using the new
Property field in the CephBlockPool Spec.
Also, this fixes the case where both `CephBlockPool` and `CephCluster`
are created at the same time. When Rook creates the pool, the cluster is
still being bootstrapped and the global option
`osd_pool_default_pg_autoscale_mode` has not bee set yet. So the pool
gets created but its `pg_autoscale_mode` property is set to `warn`
instead of `on`.

When running Octopus, we still need to turn on the balancer module. The
distinction is tricky, the module is "enabled" but it has to be "turned
on" and configured.
This was only working when the `pg_autoscaler` module was explicitly
listed in the CephCluster spec mgr section module section but not
automatically configured when running Octopus (the `pg_autoscaler`
module is already enabled).
