Update Getting Started guide to remove submodule init

Since all the dependencies of fjord are installed in a virtualenv
during provisioning, we no longer need to pull in the submodules. Yay!
A lot of time saved!

[bug 1045623] Overhaul rate limiting and update limits

* reworks all the code so that we're using django-ratelimit as the core
  of our throttling instead of django-ratelimit for some things and
  django-rest-framework's throttling stuff for other things
* move throttling-related things from the feedback app to the base app
* change throttling from 100/h to 50/h for all posting (api and non-api)
* add throttling to the hb posting of 50/h
* add double-submit throttling to the api posting of 1/10m
* change double-submit throttling for non-api posting to 1/10m
Fix response view

The errors display code was all messed up for some reason.
Fix rulename

I changed the rate limit on this rule, but didn't adjust the rulename.
This adjusts that so it shows up in graphite correctly.
[bug 1051214] Clean up DRF rate limiting code

This removes some code in the DRF rate limiter we have with the hope
that it makes it more likely it does a statsd call.

Add anonymize script

This reduces the PII in a local database, but probably doesn't eliminate
it. This does **not** make a database ready for public use. It does
reduce the amount of PII from a copied db.
