Implement Janrain Capture and Janrain Engage auth provider

[AndrewLane]

Fixes #2398

An addition to parse server to allow for authentication using Janrain. Janrain provides an Engage product as well as a Capture product, so there will be separate auth providers for each. It would be similar to Twitter, Facebook, etc. which are already implemented.

1) Janrain Engage Configuration:

The Janrain Engage API Key can be provided to Parse Server via configuration like:

{
    "appId": "...",
    "masterKey": "...",
    "databaseURI": "...",
    /* ... */
    "oauth": {
        "janrainengage": {
            "api_key": "your_api_key_here"
        }            
    }
}

2) Janrain Engage Auth Request

The POST to /users looks like:

{
    "authData": {
        "janrainengage": {
            "id": "social_id_here",
            "auth_token": "janrain_engage_auth_token_here"
        }
    }
}

3) Janrain Capture Configuration:

The Janrain Capture host can be provided to Parse Server via configuration like:

{
    "appId": "...",
    "masterKey": "...",
    "databaseURI": "...",
    /* ... */
    "oauth": {
        "janraincapture": {
            "janrain_capture_host": "your-janrain-capture-host.janraincapture.com"
        }            
    }
}

4) Janrain Capture Auth Request

The POST to /users looks like:

{
    "authData": {
        "janraincapture": {
            "id": "janrain_capture_id",
            "access_token": "janrain_capture_access_token"
        }
    }
}

Whoops, I added a breaking unit test. Sorry for the amateur hour. Will get that fixed.
