Description

Pending operations on an agent should be transitioned to `OPERATION_UNREACHABLE` when an agent is marked unreachable. We should also make sure that we pro-actively send operation status updates for these operations when the agent becomes unreachable.

We should also make sure that we send new operation updates if/when the agent reconnects - perhaps this is already accomplished with the existing operation update logic in the agent?
