Do not run heat/tools/nova_create_flavors.sh

This script takes a long time to run which will affect tempest
run times. Instead of running this, example templates will be modified
to align with the default heat flavors.

Clean up horizon apache logs on unstack

It feels like the right think to do. Moreover it will avoid to display
horizon errors from a previous devstack run that would be displayed because
of the tail -f in start_horizon()

xenapi: Ubuntu installation repository/proxy fix

Get rid of UBUNTU_INST_REPOSITORY, use UBUNTU_INST_HTTP_HOSTNAME and
UBUNTU_INST_HTTP_DIRECTORY instead. User can also specify
UBUNTU_INST_HTTP_PROXY to utilize a proxy for the OpenStack VM
installation. The answer file will be edited to contain the specified
values. Also get rid of the magic, undocumented MIRROR variable.

This is related to blueprint xenapi-devstack-cleanup

Do not run selinux commands if it is disabled.

 * Execution of the setenforce command when selinux was not enabled
   was resulting in a non-zero exit status, which halted devstack.

add support for changing cinder perodic_interval

As discovered in tempest, when you create and delete volumes
quickly, and have a small volume storage pool, you can get cinder
scheduler to think you are "out of space" when you are not.

This is because cinder scheduler updates free space on it's
periodic job, which defaults to 60 seconds. We need control over
that value for the devstack gate otherwise we regularly get
overruns if we run too many volume tests quickly.

Work around for bug 1180976

Expect that this will get removed later if cinder gets a more
efficient way to update the scheduler for freed resources.

Also, don't be completely stupid about setting defaults....
