Task Manager

[wtgee]

Adding a celery task manager that will become the basis for much of the future POCS operation. Maybe. ;)

For now the simple command line utilities will start and stop the messaging (rabbitmq) and results backend (redis) using the python docker sdk.

Usage: pocs tasks [OPTIONS] COMMAND [ARGS]...

  Interact with the TaskManager.

Options:
  --help  Show this message and exit.

Commands:
  start-backends  Start the celery backends specified by the config.
  stop-backends   Stop the running celery backends specified by the config.

Description

The celery distributed task manager will allow for a number of tasks to be run in a distributed manner. For the POCS core this can include things that need knowledge of the time (e.g. startup at sunset rather than issue a sleep timer at sundown), but can also start to serve as the basis for distributed hardware control (e.g. the forth-coming task-based gphto2 camera class).
