[Feature] Performance improvements for Task throughput

[shawn-hurley]

We need to re-architecture the RCM/Agents/TaskRunner to make performance improvements possible:

1. Agents should NEVER update the filesystem directly, the changes should be done in the task runner.
2. The TaskRunner, should call the RCM on "Commit" in such a way that the files are then updated on disk.
3. The RCM locks on commit, and will not unlock until validators have been completed.
4. We want some way, on commit, that if the task has been fixed, the commit is thrown away.

This would allow us to then move the task and task runner to be async and for the task manager to run tasks in parallel.
