It would be useful to be able to access the current overall memory usage of the qdrouterd process via management.
This proposal would include
- add a in-use memory gauge to the org.apache.qpid.dispatch.router entity
- add a max available memory gauge to the same entity (optional)
- integrate these values into the qdstat -m output
These gauges should report back "0" if the platform does not provide the ability to access these metrics in process.
