Bugs: ASTERISK-21283 and ASTERISK-21586
    https://issues.asterisk.org/jira/browse/ASTERISK-21283
    https://issues.asterisk.org/jira/browse/ASTERISK-21586


Repository: Asterisk


Description
-------

(depends on https://reviewboard.asterisk.org/r/2530)

This patch implements the REST API's for POST /channels/{channelId}/play
and GET /playback/{playbackId}.

This allows an external application to initiate playback of a sound on a
channel while the channel is in the Stasis application.

/play commands are issued asynchronously, and return immediately with
the URL of the associated /playback resource. Playback commands queue up,
playing in succession. The /playback resource shows the state of a
playback operation as enqueued, playing or complete. (Although the
operation will only be in the 'complete' state for a very short time,
since it is almost immediately freed up).
