Add the token issuer web service

The token issuer is implemented as a Firebase Cloud Function. The
function issues JsonWebSignatures using RS256.

Only authenticated users can get a token. This is done by checking the
`context.auth` property of each incoming request.

The API takes a `nonce` and a `deviceId` as inputs for now; but it can
be easily extended in case more fine-grained control is needed.

See more details in `server/HOW_TO.md`.
