* Refactor: findRequestingFrame

* INFO instead of WARN for NotEntitledException.

Some of these are expected, so an INFO seems more appropriate.

The stack trace tends to attract attention even when entitlements are not the
cause of a problem, so let's avoid the stack trace, but still include stack
frame info from the frame of interest.

* Use child loggers for Not Entitled logs

* Use warn, and include compoenent name

* Fix ALL_UNNAMED

* Mute entitlement warnings from repositories

* PR feedback

* Common out the Not Entitled prefix.

We're alerting on this, so let's not rely on every caller of notEntitled to remember it.
