ECOM-2572

starting to turn analytics_single into a single-box sandbox playbook

Refactoring and cleanups that resulted from DEVOPS-3068

Updated programs role to support static assets

edxlocal is too generic and does a lot of things.  This is the beginning
of separating it into roles that are more single purpose and easier to
understand.

This sets up the 10gen ubuntu package repo and installs 3.0.7 clients
from there (rather than using the 2.0 clients which ship with Ubuntu).

This uses a combination of the new tags we decided on as well as
extending the internal tags so you can do just scripts:mysql or
scripts:mongodb rather than updating all the scripts.

Fix insights DB name to use the right variable

ECOM-2559

Remove `edx-west` directory

Added programs service to sandboxes

This directory was used for Stanford's plays. While it made sense at the
time, it should no longer be neccessary to store this upstream, given
that we maintain an in-house fork/repository anyway.
