Update Vagrantfiles

(cherry picked from commit 8d1a52fe)

The API changed slightly.

Use the ubuntu keyserver to retrieve the edX PPA key.

Explicitly set the permissions for the supervisor config for celery.

Upgrade to 3.0.14

The sed -E still doesn't work on OS-X

Feanil/fix notifier celery process leak

Ansible2 compatibility and jenkins plugin updates

This was leaving \ in the generated files, which broke Jenkins

Noticed when something that worked for Feanil didn't work for Michael

In 7cd04db1 this was updated to rely less on gnu sed, but it still
didn't work properly on the sed shipped with OS-X Sierra.  gsed does,
but I don't want people to need to install that.

Error was that (:\S*)? was only matching : not :tagname, so the
generated Docker file was foo:testbar rather than foo:test

We set LANG in lms.conf and cms.conf but missed it for Celery

We already do this in the common role but not in bootstrap or abbey roles.

- Added file to allow bower to install as root

update c++ lib for android on xenial

Having the intermediate shell script causes the signals to not
propagate correctly.  So when supervisor stops the workers the
celery root process dies but the actual workers hang around. On
sandboxes this results in there eventually being lots of stray
workers that eventually chew through all the memory on the box.

added celery queue variable

Handle the edxapp worker case with two ASGs but no ELBs

There's actually 3 layers of quoting here so using some single quotes.

The end result in the file was previously
`export GO_SERVER_SYSTEM_PROPERTIES="-Dgo.config.repo.gc.cron="0 0 2 ? * SAT" go.config.repo.gc.periodic="Y""`

Note how the open quote after the equal gets closed by the quote after `cron=`.  This is not what we want.
The new output looks like this:
`export GO_SERVER_SYSTEM_PROPERTIES='-Dgo.config.repo.gc.cron="0 0 2 ? * SAT" -Dgo.config.repo.gc.periodic="Y"'`

Single quoting all the double quotes on that line.

Make sure we have pip and pip3 at the right version pointing to the r…

TNL-6510: Initialize elasticsearch for forums.

Previously it would exit without a message but no inventory.
