Scale limit testing on a 64 node cluster with 13 TB RAM and 2600
cores showed that atleast 1800 database connections are required
to appropriately start 2000 virtual machines simulateounsly.  Other
documentation on the internet recommends larger values such as 8000,
so we set to a larger value that should be able to handle a maxed out
512GB ram per compute node cluster with all services enabled.

Kolla recommends LTS wily kernel version 4.2 on Ubuntu 14.04.

http://docs.openstack.org/developer/kolla/quickstart.html#installing-dependencies



The precheck check the running kernel version, because checking
the linux-image-generic-lts-wily cannot be a valid check.

The package (linux-image-generic-lts-wily) can be installed, but
the running kernel can be other version.

With the reorganization of the MariaDB repository, the C libraries
for mariadb were not included in the toolbox container.  This results
in a non-functional CentOS environment which is resolved by this
simple patch.

This reverts commit 17e0de6a.

This change should have never merged. There is something else going on
here and the bug doesnt fully invetigate the issue. Using a mix of
system and pip packages is not acceptable and can cause problems.
In this case the packaged mysql has a KNOWN issue that we fixed in
liberty by switching to the pip installed package.

Add a glance_service_groups variable containers the container name,
service name and group name. In this way, we can remove lots of
duplicated lines.

Only copy the necessary config files when it _really_ needed. This

A recent change related to sudo securepath broke how sudo -E
works.  Now the PATH is reset by sudo as set by tox.  As a result
we can no longer rely on sudo -E anywhere in our gating system
relating to path inheritence from the parent shell.

This patch uses a shell operation in the setup_nodes.yml code
to chmod the docker socket to 666 so docker containers can build
properly.  Now docker operations don't return a permission denied
and we no longer require the sudo -E operation in any of our tox
scripts.  This isn't a security vulnerability because our gate
scripts are only meant to be run in OpenStack infrastructure.
To make this more clear I recommend moving these shell scripts to
tests/gate.
