Explicily enable the stores used by devstack

Devstack currently relies on the default value of the `known_stores`
configuration option. This patch enables explicitly the default stores
used by devstack.

The real fix for the issue below will land in Glance. However, since the
default stores will be FS and HTTP we need devstack to enable Swift's as
well, which is required in the gates, hence this patch.

Backport 'Make stop_swift() more robust for Grenade'

stop_swift() wasn't calling screen_stop() so the pid files and screen
sessions were not being cleaned up.  DevStack doesn't really care but
Grenade does for the 'base' copy of DevStack.  This is backported
to stable/havana for this reason.

Disable file injection by default

File injection in libvirt is problematic in havana on some systems.
When doing a live upgrade where the system suddenly gains libguestfs
support, a compute node may start using it, and thus start breaking.

disconnect novnc from gitbase

It turns out that grenade sets gitbase, however some of our
repositories don't have git.openstack.org repos. This causes a
really interesting failure case with grenade because novnc checkout
fails, then it does a checkout to master of nova.

split up stop_nova to isolate stop_nova_compute

Split stop_nova into: stop_nova_compute and stop_nova_rest. This is
needed to support the partial-ncpu grenade test where we want to stop
everything but nova_compute.

Xfsprogs package has been installed. This is the cause of the error
stack does not have
permission to perform mkfs.xfs command rather mkfs.xfs command in /sbin/

match devstack-gate format

support millisecond resolution and the | separator for ts vs.

everything else in openstack is running at millisecond resolution,
and some times it's actually useful to see that when debugging
gate failures.
