582d004ca5 util: store EnvVaultInsecure as string, not bool
The configuration option `EnvVaultInsecure` is expected to be a string,
not a boolean. By converting the bool back to a string (after
verification), it is now possible to skip the certificate validation
check by setting `vaultCAVerify: false` in the Vault configuration.

Fixes: #1852

df81022349 rbd: add support for VAULT_SKIP_VERIFY in KMS ConfigMap
When the KMS VaultTokens is configured through a Kubernetens ConfigMap,
the `VAULT_SKIP_VERIFY` option was not taken into account. The option
maps to the `vaultCAVerify` value in the configuration file, but has the
reverse meaning.

b3fbcb9c95 rbd: read configuration from the configmap
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.

e4b16a5c72 util: allow tenants to (re)configure VaultTokens settings
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

8f91c672d4 util: add EncryptionKMS.Destroy()
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().

8d3a44d0c4 rbd: add minsnapshotsonimage flag
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.
