pulling out the github requirements

edxapp migrations to run are now seperated in to file per database

Allow ecommerce gunicorn workers to be regularly restarted

Added grading policy api url.

Copy XBlock configuraiton files to the remote server

Adding Analytics API report download endpoint variables

Add edx-east explanation.

Adds INSIGHTS_LEARNER_API_LIST_DOWNLOAD_FIELDS

Add ability to encrypt splunk traffic

Add box files for eucalyptus.2

Splunk already monitors its own logs, so installing splunkforwarder is
redundant. Also, the splunkforwarder role only works on ubuntu and the
splunk server runs on ec2linux (which is redhat-based).

add default configuration for neo4j

Now the install happens in the current directory, with logs in a 'logs'
subdirectory.

Other improvements: curl now fails if the Vagrantfile can't be
downloaded, because the RELEASE value is invalid.  Curl also doesn't
print as large a progress bar.  The script fails early if there's no
RELEASE specified.

Add an OEP-2 compliant openedx.yaml file

Docker workaround for ansible provisioning.

Add task to take tags from the instance and put them on the AMI

This is simpler than doing the scp ourselves and passing a remote path
to ansible-playbook.  It will also simplify any future jenkins jobs we
may end up with.

add symlink to jarsigner for cleaner scripting

Merge all Eucalyptus changes to master.

Config location was also incorrect.
