Code review comment for lp:~bac/juju-gui/1096230

*** Submitted:

Add support for _annotation calls to env.

The calls update_annotations, get_annotations, and remove_annotations
are
added to the env object.

As a drive-by, in test_env.js the unnecessary use of async calls was
eliminated by removing the 'done' parameter. Leaving it in place where
not
required was confusing.
