Jingjing Ren d746c2bdc9 Handle glanceclient CommunicationError in horizon
When glanceclient throws a CommunicationError,
Horizon doesn't show the error message from the exception
handling code because the exception type CommunicationError
is not recognized.

This change registers the exception type and
adds a unit test case.
