Do not install mysql if mariadb is installed on openSUSE

mariadb and mysql are conflicting on a package level, but are compatible
for our needs. So if mariadb is already installed, do not try to install
mysql.

Modify startup order of Cinder services.

There are cases where the timing between the start up
for cinder-volume and cinder-scheduler service can result
in a race where the scheduler doesn't know about the volume-service
until the next periodic update.

This change does attempts to do an easy fix by swapping the start
order of the cinder services to ensure that the scheduler will be
able to receive the volume service capabilities update.

Disable fallocate and set max_file_size to default

- We used to set max_file_size to 10000 to get the functional tests
  passing on devstack but this was the wrong way. We are now disabling
  fallocate like done in saio to get the large objects test passing.
- Fixes bug 1201077.

Only create swift account if swift enabled

Only call the swift account creation function if swift is enabled,
otherwise the endpoints are created in keystone even though swift
isn't running.

This causes failures when tempest queries keystone and thinks swift is
there; it starts running tests against it that fail with unhelpful
"connection refused" errors.
