RT, reference tracker, is key-based implementation of a reference counter.
Unlike an integer-based counter, RT counts references by tracking unique
keys. This allows accounting in situations where idempotency must be
preserved. It guarantees there will be no duplicit increments or decrements
of the counter.

Mounts managed by ceph-fuse may get corrupted by e.g. the ceph-fuse process
exiting abruptly, or its parent container being terminated, taking down its
child processes with it.
This commit adds checks to NodeStageVolume and NodePublishVolume procedures
to detect whether a mountpoint in staging_target_path and/or target_path is
corrupted, and remount is performed if corruption is detected.

This commit adds a couple of helper functions to parse the migration
request secret and set it for further csi driver operations.
More details:
The intree secret has a data field called "key" which is the base64
admin secret key. The ceph CSI driver currently expect the secret to
contain data field "UserKey" for the equivalant. The CSI driver also
expect the "UserID" field which is not available in the in-tree secret
by deafult. This missing userID will be filled (if the username differ
than 'admin') in the migration secret as 'adminId' field in the
migration request, this commit adds the logic to parse this migration
secret as below:
"key" field value will be picked up from the migraion secret to "UserKey"
field.
"adminId" field value will be picked up from the migration secret to "UserID"
field
if `adminId` field is nil or not set, `UserID` field will be filled with
default value ie `admin`.The above logic get activated only when the secret
is a migration secret, otherwise skipped to the normal workflow as we have
today.

the migration nodestage request does not carry the 'clusterID' in it
and only monitors are available with the volumeContext. The volume
context flag 'migration=true' and 'static=true' flags allow us to
fill 'clusterID' from the passed in monitors to the volume Context,so
that rest of the static operations on nodestage can be proceeded as we
do treat static volumes today.

as part of migration support, the clusterID has to be fetched
from passed in mon. Because the intree RBD storage class only
got monitor and not `clusterID` parameter support. However, in
CSI, SC has the `clusterID` parameter support but not mon. Due
to that we have to fetch the clusterID from config file for the
passed in mon and use it in our operations. This adds a helper
function to retrieve clusterID from passed in mon string.

This commit adds capability to genVolFromVolumeOptions() to fetch
mapped clusted-id & mon ips for mirrored PVC on secondary cluster
which may have different cluster-id.
This is required for NodeStageVolume().
We also don't need to check for mapping during volume create requests,
so it can be disabled by passing a bool checkClusterIDMapping as false.
GetMonsAndClusterID() is modified to accept bool checkClusterIDMapping
based on which clustermapping is checked to fetch mapped cluster-id and
mon-ips.

When NewK8sClient() detects and error, it used to call FatalLogMsg()
which causes a panic. There are additional features that can be used on
Kubernetes clusters, but these are not a requirement for most
functionalities of the driver.
Instead of causing a panic, returning an error should suffice. This
allows using the driver on non-Kubernetes clusters again.

A new "internal/kms" package is introduced, it holds the API that can be
consumed by the RBD components.
The KMS providers are currently in the same package as the API. With
later follow-up changes the providers will be placed in their own
sub-package.
Because of the name of the package "kms", the types, functions and
structs inside the package should not be prefixed with KMS anymore:
internal/kms/kms.go:213:6: type name will be used as kms.KMSInitializerArgs by other packages, and that stutters; consider calling this InitializerArgs (golint)

By placing the NewK8sClient() function in its own package, the KMS API
can be split from the "internal/util" package. Some of the KMS providers
use the NewK8sClient() function, and this causes circular dependencies
between "internal/utils" -> "internal/kms" -> "internal/utils", which
are not alowed in Go.

Moving the log functions into its own internal/util/log package makes it
possible to split out the humongous internal/util packages in further
smaller pieces. This reduces the inter-dependencies between utility
functions and components, preventing circular dependencies which are not

Unit-testing often fails due to a race condition while writing the
clusterMappingConfigFile from multiple go-routines at the same time.

By splitting the public GetClusterMappingInfo() function into an
internal getClusterMappingInfo() that takes a filename, unit-testing can
use different files for each go-routine, and testing becomes more
predictable.

Hashicorp Vault does not completely remove the secrets in a kv-v2
backend when the keys are deleted. The metadata of the keys will be
kept, and it is possible to recover the contents of the keys afterwards.
With the new `vaultDestroyKeys` configuration parameter, this behaviour
can now be selected. By default the parameter will be set to `true`,
indicating that the keys and contents should completely be destroyed.
Setting it to any other value will make it possible to recover the
deleted keys.
