82557e3f34 util: allow configuring VAULT_BACKEND for Vault connection
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.

43f753760b cleanup: resolve nlreturn linter issues
nlreturn linter requires a new line before return
and branch statements except when the return is alone
inside a statement group (such as an if statement) to
increase code clarity. This commit addresses such issues.

Updates: #1586

6dc5bf2b29 util: split vaultTenantConnection from VaultTokensKMS
This makes the Tenant configuration for Hashicorp Vault KMS connections
more modular. Additional KMS implementations that use Hashicorp Vault
with per-Tenant options can re-use the new vaultTenantConnection.

eea97ca014 util: move GetID() from EncryptionKMS to VolumeEncryption
There is no need for each EncryptionKMS to implement the same GetID()
function. We have a VolumeEncryption type that is more suitable for
keeping track of the KMS-ID that was used to get the configuration of
the KMS.

This does not change any metadata that is stored anywhere.

9317e2afb4 util: rewrite GetKMS() to use KMS provider plugin API
GetKMS() is the public API that initilizes the KMS providers on demand.
Each provider identifies itself with a KMS-Type, and adds its own
initialization function to a switch/case construct. This is not well
maintainable.

The new GetKMS() can be used the same way, but uses the new kmsManager
interface to create and configure the KMS provider instances.

All existing KMS providers are converted to use the new kmsManager
plugins API.

a42c4b5855 util: convert VAULT_SKIP_VERIFY to "vaultCAVerify" KMS option
"VAULT_SKIP_VERIFY" is a standard Hashicorp Vault environment variable
(a string) that needs to get converted to the "vaultCAVerify"
configuration option in the Ceph-CSI format.

The value of "VAULT_SKIP_VERIFY" means the reverse of "vaultCAVerify",
this part was missing in the original conversion too.
