Problem: When a power operation cannot be done due to an issue with the hierarchy, a very general "ancestor off" or "ancestor error" is returned. This does not provide alot of detail to users.
Update the error message to be of the form
cannot perform <op>, dependency <issue> (host=<host>, plug=<plug>)
for example
cannot perform on, dependency off (host=cmm plug=Enclosure)
Update tests for new error message.
Fixes #153
