if the kms encryption configmap is not mounted
as a volume to the CSI pods, add the code to
read the configuration from the kubernetes. Later
the code to fetch the configmap will be moved to
the new sidecar which is will talk to respective
CO to fetch the encryption configurations.
The k8s configmap uses the standard vault spefic
names to add the configurations. this will be converted
back to the CSI configurations.

A tenant can place a ConfigMap in their Kubernetes Namespace with
configuration options that differ from the global (by the Storage Admin
set) values.
The ConfigMap needs to be located in the Tenants namespace, as described
in the documentation

and the client certificate key for the vault token
based encryption.

Tenants (Kubernetes Namespaces) can use their own Vault Token to manage
the encryption keys for PVCs. The working is documented in #1743.

Add a new method to the EncryptionKMS interface so that resources can be
freed when EncryptionKMS instances get freed.
With the move to using the libopenstorage API, a temporary file needs to
store the optional CA certificate. The Destroy() method of the
vaultConnection type now removes this file.
The rbdVolume uses the EncryptionKMS type now, so call the new Destroy()
method from withing rbdVolume.Destroy().

Make it possible to calle initConnection() multiple times. This enables
the VaultTokensKMS type to override global settings with options from a
per-tenant configuration.

This makes it possible to pass a more complex configuration to the
initialize functions for KMS's. The upcoming VaultTokensKMS can use
overrides for configiration options on a per tenant basis. Without this
change, it would not be possible to consume the JSON configuration file.

In order to re-use the configuration of Vault, split a new
vaultConnection type from the VaultKMS type.

Instead of the hand-rolled Vault usage, use the libopenstorage/secrets
package that provides a nice API. The support for Vault becomes much
simpler and maintainable that way.

An rbd image can have a maximum number of
snapshots defined by maxsnapshotsonimage
On the limit is reached the cephcsi will
start flattening the older snapshots and
returns the ABORT error message, The Request
comes after this as to wait till all the
images are flattened (this will increase the
PVC creation time. Instead of waiting till
the maximum snapshots on an RBD image, we can
have a soft limit, once the limit reached
cephcsi will start flattening the task to
break the chain. With this PVC creation time
will only be affected when the hard limit
(minsnapshotsonimage) reached.

We have below exported function in credentials.go which is not
called from anywhere in the repo. Removing it for the same reason.
```
// NewCredentials generates new credentials when id and key
// are provided.
func NewCredentials(id, key string) (*Credentials, error) {

The go-ceph CephFS Admin API needs a rados.Conn to connect the Admin
interface to the Ceph cluster. As the rados.Conn is internal to the
ClusterConnection type, add GetFSAdmin() to create a new FSAdmin
instance for a specific connection.
