In https://review.openstack.org/535252 the installation
process for the role was simplified, but an unintentional
side-effect was to removed the previously included support
for installing the extra percona packages when installing
on the ppc64le platform.
This patch re-introduces that ability, but scopes it to
only execute on that hardware platform, and only for Ubuntu.
The download is, by default, facilitated through the deploy
node (rather than the target nodes) so that the download
is done once, then pushed to the targets. This can be
adjusted with the right parameters to download from the
targets instead.
Also, in https://review.openstack.org/543888 adjustments
were made to disable compression/qpress on architectures
other than x86_64, and to fail the role execution if it
was enabled on any other architecture. This has been
corrected to ensure that compression is enabled by default
for ppc64le on Ubuntu, and enabled by default for x86_64,
but disabled by default for all other combinations. The
fail task is adjusted appropriately and moved to the main
task file so that it executes and fails out before any
changes are made.
