hooks: Add debug logging for initial hook loading

Browse Source 
We've had logrus logging in the monitor code since it landed in
68eb128f (pkg/hooks: Version the hook structure and add 1.0.0 hooks,
2018-04-27, #686).  This commit adds similar logging to the initial
hook.New() and Manager.Hooks() calls to make it easier to see if those
are working as expected.
