Vault agent Auto-Auth JWT method

The jwt method reads in a JWT from a file and sends it to the JWT Auth method.

Configuration

• path (string: required) - The path to the JWT file

• role (string: required) - The role to authenticate against on Vault

• remove_jwt_after_reading (bool: optional, defaults to true) - This can be set to false to disable the default behavior of removing the JWT after it's been read.
