* initial commit of streams * refactor stream component * refactor so stream formats are not considered a platform * initial test and minor refactor * fix linting * update requirements * need av in tests as well * fix import in class def vs method * fix travis and docker builds * address code review comments * fix logger, add stream start/stop logs, listen to HASS stop * address additional code review comments * beef up tests * fix tests * fix lint * add stream_source to onvif camera * address pr comments * add keepalive to camera play_stream service * remove keepalive and move import * implement registry and have output provider remove itself from stream after idle, set libav log level to error
