Auth persist api

[telday]

Desired Outcome

Adds a new API collection which allows users to configure a policy/secret values for an authentication webservice with one HTTP request.

Implemented Changes

Adds a new route to Conjur (POST /authenticators/:account/persist) which accepts a JSON object in the body:

{
    "authenticator": "<authenticator type>",
    "service-id": "<authenticator service  id>",
    <variables>
}

@telday, I was playing with this a bit on Friday and before we get this in, we need to standardize the URLs to conform both to our current authenticator standards, but also REST best practices. Can you please break each authenticator "create" into the following convention:

POST https://{Conjur-server-hostname}/authn-{type}/{service-id}/{account}

The JSON body should be updated to remove the service_id from the doc (as it's now in the URI).
