When it is known some features have not activated fully, do not return 401

Typical case is in High Availability testing. One cluster member has been rebooted and it is starting again. Not every AAA bundle is ready, so restconf returns 401.

In reality, the user probably is allowed to access the resource, so 401 may be misleading. Restconf could wait until AAA is ready (or a timeout expires).

Setting severity to minor, as this only happens shortly after boot, and it may not be easy to figure out when exactly AAA becomes ready.

It is possible that AAA project has authority on HTTP processing at this stage, in which case this is a AAA Improvement.
