Update build jenkins plugins

Bump installed jenkins_master version

It looks like this version disappeared from the downloads page within
the past few weeks. I successfully ran this play less than a month ago,
but it started failing a week or two ago, due to the 404 upon download.

I'm admittedly a bit confused as to why there appears to be at least 3
different minor versions of jenkins in use [1][2][3] (plus a major bump
on the build server?! [4]), so I simply cribbed the version used by the
`tools_jenkins` role.

References:
- [1] jenkins_version: "1.638"
- [2] jenkins_tools_version: "1.651.3"
- [3] jenkins_admin_version: "1.658"
- [4] build_jenkins_version: jenkins_2.60.3

add DEFAULT_COURSE_VISIBILITY_IN_CATALOG

ENH: extra vars to update.sh

Make it so we update alarms even when they already exist.

We don't need to pin back setuptools anymore

Add a new playbook to just install splunk forwarder

We can just use whatever version comes in with the venv setup safely

Install OpenStack Python requirements if using OpenStack settings

These were copied from old lms and seem unneeded

Allow the xqueue session engine to be configurable.

XQueue really doesn't make things like graphviz graphs, or use apparmor
(that's done in xserver or xqwatcher I believe)

We removed use of these templates after platform removed yaml

While we'll eventually switch back, having unused templates around is
confusing.

Other code removed in 8f16fd28

This defaults to http://localhost:18040 but needs internal hostname

Update sqoop 1.4.6 package download url

XQueue wasn't using this argument and it was removed

* Updating analytics jenkins role to work again, and to be more consistent with current codebase patterns

* Updating analytics jenkins role to work again, and to be more consistent with current codebase patterns. Moved jenkins.j2 to the directory with other j2 templates

It now throws an error from Django if you pass in the unused parameter.

* Add credentials-binding plugin to analytics jenkins

* Remove custom jenkins_plugin that no longer exists

Upgrade mongo agent (OPS-2290)

Add an xqueue_env file

Consolidate edxapp update assets scripts.

The asset compilation scripts edxapp-update-assets-lms and
edxapp-update-assets-cms duplicate a lot of work between them. Running
webpack twice also seems to cause an intermittent error where the
second build results in a different bundle hash than the first.

It is possible to run "paver update_assets" without specifying "lms" or
"cms", in which case it just compiles it all at the same time. This
removes the duplicate invocations of webpack and should speed the build
overall.

Much of our deployment infrastructure relies on having the settings and
path controlled from the environment file.  We don't have a good
way yet to define the CONFIG file since there is an auth and an env.
There's a later ticket for that.
