Matt Leung 79428aa231 Enable Vault auth through kubernetes auth method
Added a feature to obtain the initial Vault token from the Kubernetes
auth method.

This works by making a request to the Vault server at the specified auth
method mount point's login path and presenting the JWT located in a file
on a running pod, along with the Kubernetes role to authenticate as.

Vault will then respond with a token and its TTL, if the request is valid.
