Gian Merlino ff325b1f65 Merger: Changes to support rolling locks and a task-action API 
Generally, TaskStatus is no longer used as the sole way for tasks to
communicate status and metadata update requests back to the
coordinator. It is still used to communicate success or failure, but a
TaskActionClient is used for all other communication. In remote mode
this uses an http api.

TaskContext no longer exists, as its purpose is now served by
the TaskActionClient.

The TaskQueue and TaskConsumer are no longer in charge of committing
stuff for a task. Instead, it happens when an action is sent in. Tasks
are expected to ensure that this is OK by making their behavior
idempotent (since they may be retried after partially completing).

One new kind of request afforded to tasks is the ability to release
and acquire arbitrary locks. This will be useful for long-running tasks.
Short-lived tasks can still be given a lock automatically upon startup
by providing a "fixed interval".

New tables when using db storage:
- tasklocks, to support persistence of arbitrary locks.
- tasklogs, to log actions taken by tasks
