Each of the Impalad web UI's should provide a way to dump the current state of the daemon (json?), preferably with the following data.

Coordinator:
- All queries in flight (with query IDs)
- Current state of each query ID, along with a timeline
- Last report time of each of the fragment instances, for each query ID
- Lock diagnostics if a query is blocked on something
- Lock diagnostics of the process level locks (like coordinator::lock_ etc..)

Executor:
- All the fragment instances running at the current time
- State of each of the fragment instances
- Backtraces of the executor nodes in the fragment instances.
- Lock diagnostics if the nodes are blocked on something
- Event timeline of each of the executor nodes
