Remove system xtrabackup package if found

[Kevin Carter]

In earlier versions of OpenStack Ansible, which includes early liberty, the system package for percona xtrabackup was being installed using either the version that came from Ubuntu or directly from the percona repo however since the liberty release we've changed to package install to come directly from a deb downloaded from the percona-xtrabackup archive. The issue is that if the system package was used the installation of the deb may fail because of potential version conflicts. To resolve this issue a task needs to be added before the deb install to ensure that the system version of the package is removed which will guarantee there are no version discrepancies upon installation of the package we know we need.

    Fix issue with system installed xtrabackup

    The change adds a task to ensure that the system provided
    xtrabackup package is removed before installing the downloaded
    version using the deb. This is required to ensure that there
    are no version conflicts when installing the package.

    The change also corrects the version of the galera server repo
    in the defaults directory. While the repo correct version of
    mariadb is being installed the name of the assumed repo is wrong.

    Closes-Bug: #1513459
