No metrics available through CLI in domain mode

Issue

• We can't get the CLI to return metrics when we try to check them in domain mode. For example, we try to check AJP metrics like so:

[domain@localhost:9999 /] cd /profile=ha/subsystem=web/connector=ajp/
[domain@localhost:9999 connector=ajp] ls
