During an upgrade, we run the upgrade in serial, and we attempt to
bootstrap the cluster from the "galera_server_bootstrap_node". This
causes issues when there is an existing cluster that is still up.
To avoid this, we can simply attempt to start the cluster normally, if
it fails to start, and join the existing cluster, we can bootstrap as
usual.
Additionally, we can make the bootstrap slightly more efficient by only
running it against the bootstrap host and splitting out the
"galera_upgrade_post.yml" tasks.
Finally - run the upgrade in serial which mirrors our approach in the
integrated repo.

Closes-Bug: #1667103
Update repos and packages to install the server for MariaDB 10.1, the
current stable release.
Several improvements have been made to improve the upgrade process and
an upgrade from 10.0 has been included in the test playbooks.
Make use of the yum_repository module for installing on yum based
systems and give the apt repository files consistent names, 'MariaDB'
and 'Percona' for easier maintenance and handling of upgrades going
forward.

This patch consumes the test scripts implemented by
https://review.openstack.org/375061 to ensure that
the tests and test preparation is consistent and
more maintainable.

Previous versions of OpenStack-Ansible allowed
for upgrading Mariadb from version 5.5 to 10.0.
Mitaka assumes Mariadb version 10.0, thus the
upgrade check is no longer needed for gate
testing.

The following changes have been made to reorganize the structure of this
role's test playbooks, bringing them into line with other
OpenStack-Ansible roles:
- move each playbook to an individual file
- rename playbooks descriptively
- define hosts and groups directly in the inventory file
- include group vars required by containers
- store extra variables in a single shared test-vars file
- remove use of the openstack_hosts role
- include callback plugin for human readable logging of test tasks

Create a new variable called galera_cluster_members which is a list of
the hosts that make up the galera cluster. Set the default value to
groups['galera_all'] which is the group used by openstack-ansible to
refer to the members of the cluster. Replace all other references to
groups['galera_all'] with the new variable. This allows other consumers
of this role to use their own group naming scheme.
Add a new task to verify that current host is a member of
galera_cluster_members.
Add the var galera_client_drop_config_file=true to the role dependency
galera_client, this is required because the default value for that var
in the galera_client role is based on membership of the galera_all
group.
Modify the functional testing to override galera_cluster_members, this
aims to prevent the return of any hard-coded role references.

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.
