To avoid subvolume leaks if the SetAllMetadata
operations fails delete the subvolume.
If any operation fails after creating the subvolume
we will remove the omap as the omap gets
removed we will need to remove the subvolume to
avoid stale resources.

A vulnerability was found in golang.org/x/text/language package which
could cause a denial of service. An attacker can craft an
Accept-Language header which ParseAcceptLanguage will take significant
time to parse.
Version v0.3.8 of golang.org/x/text fixes a vulnerability.

This commit makes the following changes:
`Please replace \":code_blocks => false\" \`
`by \":ignore_code_blocks => true\" in your configuration.`
Some rules are ignore for the time being,
these will be fixed later on.

Different places have different meaningful fallback. When parsing
from user we should default to block, when parsing stored config we
should default to invalid and handle that as an error.

Use constant protector name 'ceph-csi' instead of constant prefix
concatenated with the volume ID. When cloning volumes the ID changes
and fscrypt protected directories become inunlockable due to the
protector name change

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.

Currently fscrypt supports policies version 1 and 2. 2 is the best
choice and was the only choice prior to this commit. This adds support
for kernels < 5.4, by selecting policy version 1 there.

Integrate google/fscrypt into Ceph CSI KMS and encryption setup. Adds
dependencies to google/fscrypt and pkg/xattr. Be as generic as
possible to support integration with both RBD and Ceph FS.
Add the following public functions:
InitializeNode: per-node initialization steps. Must be called
before Unlock at least once.
Unlock: All steps necessary to unlock an encrypted directory including
setting it up initially.
IsDirectoryUnlocked: Test if directory is really encrypted

Add GetSecret() to allow direct access to passphrases without KDF and
wrapping by a DEKStore.
This will be used by fscrypt, which has its own KDF and wrapping. It
will allow users to take a k8s secret, for example, and use that
directly as a password in fscrypt.
