Add a whole suite of tests for phone and email alerts. Small update
to a few unit tests for alert views.

Small fixes to the main "index" view for alerts. Move the
manage_password page for LV-EM observers to the ligoauth app and
show a link to it from the navbar to those users.

* Filter available contacts for a notification to be verified
  contacts belonging to the user
* New better code for handling label queries
* Some better help text for notification forms
* Remove old notification forms and views

New model functionality, better forms and views.

Separate phone and email contacts, add verification of contact
information, improve views and forms.

Also squash migrations in the alerts app.

Previously forgot to add deepclean and gwhen robot users to the
LVC group.

Since the web view makes a few API requests to load log messages and
other content, we have to allow more requests. Also, it sounds like
users at a university might all appear to be on the same IP address,
so we want to try to account for that.

Not working as expected, so we are going to have to revisit this
feature in the near future.
