This patch adds eslint, a permissively licensed (as opposed to
jshint or jslint) javascript style linter. It also enables the use
of 'npm run lint', which may be used in OpenStack's gate to
cause build failures when improperly formed javascript is
committed.
Existing javascript was updated to pass linting rules. Note
that most of these changes were formatting and file length
concerns. The noted stylistic change that we should probably
discuss is the use of singlequote vs. doublequote. Single is
the pep8 standard used in python, and thus enforcing that
seems to make the most sense.
