This commit adds `GetCephFSRadosNamespace` util method that returns
the `RadosNamespace` specified in ceph-csi-config ConfigMap under
cephFS.radosNamespace.
If not specified, the method returns the default RadosNamespace
i.e, csi.

For core K8s API objects like Pods, Nodes, etc., we
can use protobuf encoding which reduces CPU consumption
related to (de)serialization, reduces overall latency
of the API call, reduces memory footprint, reduces the
amount of work performed by the GC and results in quicker
propagation of objects to event handlers of shared informers.

This commit resolves the govet issue -
`copylocks: call of append copies lock value ... contains sync.Mutex`
Embedding DoNotCopy in a struct is a convention to signal and prevent
shallow copies, as recommended in Go's best practices. This does not
rely on a language feature but is instead a special case within the vet
checker.

The only encoding version that exists is `1`. There is no need to have
multiple constants for that version across different packages. Because
there is only one version, `GenerateVolID()` does not really require it,
and it can use a default version.
If there is a need in the future to support an other encoding version,
this can be revisited with a cleaner solution.

Padding a passphrase with null chars to arrive at a 32-byte length
later forces a user to also pass null chars via the term when
attempting to manually unlock a subvolume via the fscrypt cli tools.
This also had a side-effect of truncating any longer length passphrase
down to a shorter 32-byte length.

Issue:
The RoundOffCephFSVolSize() function omits the fractional
part when calculating the size for cephfs volumes, leading
to the created volume capacity to be lesser than the requested
volume capacity.
Fix:
Consider the fractional part during the size calculation so the
rounded off volume size will be greater than or equal to the
requested volume size.

Fixes: #4179
By default, `cryptsetup luksFormat` uses Argon2i as Password-Based Key
Derivation Function (PBKDF), which not only has a CPU cost, but also a memory
cost (to make brute-force attacks harder).
The memory cost is based on the available system memory by default, which in
the context of Ceph CSI can be a problem for two reasons:
1. Pods can have a memory limit (much lower that the memory available on the
node, usually) which isn't taken into account by `cryptsetup`, so it can get
OOM-killed when formating a new volume;
2. The amount of memory that was used during `cryptsetup luksFormat` will then
be needed for `cryptsetup luksOpen`, so if the volume was formated on a node
with a lot of memory, but then needs to be opened on a different node with
less memory, `cryptsetup` will get OOM-killed.
This commit sets the PBKDF memory limit to a fixed value to ensure consistent
memory usage regardless of the specifications of the nodes where the volume
happens to be formatted in the first place.
The limit is set to a relatively low value (32 MiB) so that the `csi-rbdplugin`
container in the `nodeplugin` pod doesn't require an extravagantly high memory
limit in order to format/open volumes (particularly with operations happening
in parallel), while at the same time not being so low as to render it
completely pointless.

NewContextFrom{Mountpoint,Path} functions use cached
`/proc/self/mountinfo` to find mounted file systems by device ID.
Since we run fscrypt as a library in a long-lived process the cached
information is likely to be stale. Stale entries may map device IDs to
mount points of already destroyed RBDs and fail context creation.
Updating the cache beforehand prevents this.
