KV (v2) engine support in Documentation

[pjohnson-ptc]

The documentation suggests the Gem supports Hashicorp Vault's KV2 engine storage, but from what I have experienced the documentation is out of date and I have been unable to utilize the gem to work with the KV2 backend engine in Vault.

I have seen several issues similar to the comment in this open issue:

Which leads me to believe this Gem is not fully supporting KV-v2 ? Can this be updated?
