Handle exceptions in management context

Browse Source 
Prior to this commit, details about an exception would get dropped when
the management context was separate from the application context and
an actuator endpoint threw a binding exception.

This commit adds some logic to capture the exception so the management
context error handlers can add the appropriate attributes to the error
response.

Fixes gh-21036
