At present generating a user dump is an asynchronous call
and does not block the user to generate another dump.
This can cause out-of-memory issues if dumps are
generated in a loop.
Adding a check to see if the user-initiated dump is
already in progress before starting another user
dump request.
Return "Unavailable" error if generate user dump request is
received while a user dump generation is in progress.
Tested:
