[AAI] Add options for remote debugging and profiling

- add debug.enabled value for enabling debugging [1]
- add profiling.enabled value for enabling probiling [2]
- only expose debug port (5005) if debug.enabled=true

[1] appropriate jvm args will be added and
the debug port will be exposed on the pod
[2] appropriate jvm args will be added and
the 9999 port used for profiling via jmx will be exposed
