pip install default prefix in Ubuntu is /usr/local, and Kolla tools scripts
didnt respect that. So I added few OS checks in this scripts.

I improve config path check in build.py. Added more verbose error if we can't
find config directory.

The commands around installing docker on Centos7
in the quickstart guide needed a little tweaking
and a little spell checking.

Use the absoluate path rather than that with `..`. This will be

The main reason for this change is to allow the DinD stuff to work. It
has limited use outside of that use case, but it may still be useful
to others in the future.

Adjust all the configs to list all the rabbitmq hosts rather than
running rabbitmq through the VIP. This is made possible by clusterer
which has already merged.

In some cases we're seeing httpd not cleaning up properly after itself,
which results in the keystone container failing to restart. This is
confirmed to happen on rpm based distros, but have not had any reports
on Ubuntu.

So we can respect DRY and share as much code as possible I have broken
out the common code between the aio and multinode gate scripts.

Additionally, this lays the ground work for removing our policy on
root-everywhere by using sudo. Once we get the non-root stuff worked
out we can gate as non-root user.

The Fedora code is no longer used and can be removed. Should it be needed in the
future the code is very similiar to CentOS. As is it will just become out of
date as the code is never excersied.
