It seems that the version of the key/value engine can not always be
detected for Hashicorp Vault. In certain cases, it is required to
configure the `VAULT_BACKEND` (or `vaultBackend`) option so that a
successful connection to the service can be made.
The `kv-v2` is the current default for development deployments of
Hashicorp Vault (what we use for automated testing). Production
deployments default to version 1 for now.

Testing encrypted PVCs does not work anymore since Kubernetes v1.21. It
seems that disabling the iss validation in Hashicorp Vault is a
relatively simple workaround that we can use instead of the more complex
securing of the environment like should be done in production
deployments.

In golang world, if you split an empty string that does not contain
the seperator, you get an array with one empty string. This results
in volumes failing to mount with "invalid feature " (note extra space
because it's trying to check if 'empty string' is a valid feature).
This patch checks if the string is empty, and if so, it just decides
to skip the entire validation and returning nothing.

Before RBD map operation, we do check the
watchers on the RBD image. In the case of
RWO volume. cephcsi makes sure only one
client is using the RBD image. If the rbd
image is mirrored, by default mirroring
daemon will add a watcher on the image
and as we are using go-ceph a watcher will
be added as we have opened the image So
we will have two watchers on an image if
mirroring is enabled. This holds when the
rbd mirror daemon is running, In case if
the mirror daemon is not running there will
be only one watcher on the rbd image
(which is placed by go-ceph image open)
we should not block the map operation if
the mirroring daemon is not running as
its Async mirroring. This commit adds a
check to make sure no more than 2 watchers
if the image is mirrored or no more than 1
watcher if it is not mirrored image.

It helps to get a stack trace when debugging issues. Certain things are
considered bugs in the code (like missing attributes in a struct), and
might cause a panic in certain occasions.
In this case, a missing string will not panic, but the behaviour will
also not be correct (DEKs getting encrypted, but unable to decrypt).
Clearly logging this as a BUG is probably better than calling panic().
