This will connect to a cluster, find the hidden secondaries and upgrade
them to the current version specified in the mongo_3_0 play.

This required the creation of a new library module since our two current
ones return rs.status and call replSetReconfig, but neither return
rs.config, and rs.config is what tells you if a host is hidden and the
priority, which are needed for this.

SERVER-22970  Background index build produces an index with mismatched
index keys and documents

This only worked by coincidence before

We were implicitly relying on mongo to return the list of members in
their _id order, which is absurd and I have no idea how we didn't catch
it previously.

We could do a little list comprehension to pull out the member with the
same _id,  but it seemed easier to just sort both lists and retain the
original intent.

GOCD Integration - an inventory file is now created when an instance is launched

Add vim configuration for devstack

Updated ansible config to increase ControlPersist (fix timeouts on long running tasks for remote hosts)

delete the user home directory as well if state is absent

Adds jenkins_protocol_https variable

Allows JENKINS_ANALYTICS_AUTH_REALM: none

Uses proxy_set_header Host $http_host

YAML style parameters passing

rewrite the edxapp role

Improvements to django_admin.sh

- Echo the command to run before running (for post-mortem debugging)
- Stop adding "--settings aws" to the end of every command, even when it
  was added to $manage earlier

Add another region to ec2.py

This appears to be the only way to ask it to look in multiple regions
since it doesn't support AWS_REGION or --region.
Alternately, we could start having independent .ini files for deploys.

MAYN-281: Update edx-configuration to support multiple theme directories

psmisc isn't on precise docker images and the jenkins roles want it.

Dockerfile for the jenkins_analytics role

Adds the memcache to all playbooks using edxlocal

Additional configuration needs to be completed (analytics jobs in public
repo, and test config files in a public repo) and then travis should be
able to start using this with minimal extra configuration.
