/**
 * Loads and manages API Auth tokens for HipChat rooms. Loads auth token for a room from a string representation:
 *
 * ${room_name_or_id}:${api_auth_token}
 *
 * e.g. 12345:TT0Xj1dPMP4rOKbza4hqP2GNEgbtv9BZWisDavy0
 *
 * Comma separate to specify tokens for multiple rooms:
 *
 * 12345:TT0Xj1dPMP4rOKbza4hqP2GNEgbtv9BZWisDavy0, 2468:P2GNEgbtv9BZWisDavy0TT0Xj1dPMP4rOKbza4hq
 *
 * If the ${room_name_or_id} component is dropped, then the token will be used as the default in the case where no token is found for a room:
 *
 * 12345:TT0Xj1dPMP4rOKbza4hqP2GNEgbtv9BZWisDavy0, 2468:P2GNEgbtv9BZWisDavy0TT0Xj1dPMP4rOKbza4hq, WisDavy0TT0Xj1dPdPMP4rOKbza4hqP2GNEgbt
 *                                                                                                                      ^
 *                                                                                                                 default token
 *
 * For HipChat API v1 use, a single notification level token will work for every room and thus only a single default token needs to be specified.
 * For HipChat API v2 use, a 'room notification' token may need to be generated for each target room
