When kube authentication is used, let's clarify the error message and
hopefully lead to a better understanding on where to look for.
It could be misleading to print "token auth" when using kube auth,
although internally a token is used (the JWT from the Service
Account).

If the KMS connection details for Vault have a VAULT_NAMESPACE we must
use it when building the vault client to auto-detect the KV internal
version.

Rook cluster-wide encryption can now use the native Kubernetes
authentication to interact with vault KMS instead of using the token
method.

When TLS is used and includes a caert, client key/cert, we need to copy
the content of the secret to a file in the operator's container
filesystem so that we can build the TLS config and thus the HTTP Client,
which reads those files.
Also, removing the files after each API call so they don't persist on
the filesystem forever.

Passing struct by value essentially gives you a copy, so when modified
within a function, the scope is then reduced to that function. Using
pointers solves that you mutate the struct as many times as you want from
anywhere.
As a result, the auto-detection of the Vault KV backend was not working
correctly.
Also, added a ton of unit tests for Vault.

Rook will now auto detect the kv version of the vault server. This
allows users not having to pass the VAULT_BACKEND configuration in the
CephCluster CR.
