Running and enabled seem redundant. Is it ever running when not enabled or visa versa?

It protects against the case of calling SetEnabled(true) multiple times. Only spawns one go routine.

Right, but you can just check if enabled is already true in that case. E.g. if enabled == running in all cases, so no need to have both.

should the documentation in https://www.nomadproject.io/docs/internals/scheduling.html be updated to reflect this new queue? |

This PR introduces a new, blocked state for evals. Evaluations are entered into the blocked state when an evaluation creates failed allocations and is moved from the blocked state into the pending state when a node has capacity to run the evaluation. In this way, a job queue is created.
