The change adds in the ability for the role to take care of a major upgrade
in a version of an installed mariadb galera cluster.
The change adds a new task file that checks if the installed version of the
galera cluster matches that of the specified major version. The role will
hard stop if there is a version mismatch and the option "galera_upgrade=true"
is not passed.

This patch updates the tox.ini the same bashate exceptions as are
currently in the OpenStack-Ansible playbook repo.
It also ensures that the linters and all lint targets work
appropriately and normalises the tox.ini configuration to use
uniform formatting.
The use of ansible.cfg is removed as there is no way of being
certain which paths can be used without reverting to an ugly
sed hack in the commands. This is why it is preferred to make
use of environment variables which make use of tox's default
substitutions instead. It's a more reliable way of achieving
the goal for the purpose of gating and testing.
The switch to using a git clone instead of ansible-galaxy to
download the plugins is due to the path spec not being able to
work in Ansible 2.x. [1]

The role was changed to make it compatible with the OpenStack
CI. The changes effect defaults, handlers, and the tests for
the role and adds gitignore/review files.
The changes essentially get the role to a state where its passing
the tests which are spinning up a galera cluster, adding users
and databases, and then testing integrity from every node. The
tests specifically ensure we're able to guarantee that after the
role runs everything works. Previously to these changes the role
assumed everything was working and nothing had been done to
guarantee cluster state.
In the handler changes, the temporary "sst" directory is cleaned up
should the handler restart fail. This ensure that a node is in a clean
state if a leftover sst directory was on the disk which would cause
a node to fail to join a cluster or bootstrap. Additionally the
environment variable "MYSQLD_STARTUP_TIMEOUT" is now being passed
into the init script because the defaults are not being sourced
at the init script runtime.
In the task changes a new configuration file, that is part of the
mariadb package, is being removed which has unforeseen options within
it causing no logs to be created.
the default option "galera_innodb_additional_mem_pool_size" was removed
because its no longer valid within MariaDB10 and we'd never caught that
error message until now.
The tests were updated to support running the role from a user which
was not root.
