XenAPI: Update DomU to Ubuntu Saucy

Driven by a race condition in LVM being hit in the tempest
tests.  This is a locking race between a file lock and a
semaphore which is fixed in 2.02.96-5.

Remove duplicate debug option from keystone-all

The keystone server was started with the options like

 keystone-all ... -d --debug ...

The -d and --debug options are the same so one of them is
redundant.

This will make it less confusing if someone removes --debug and
thinks that debug is off, but debug is still on because they
didn't notice there was an extra -d.

HEAT_FETCHED_TEST_IMAGE may not be defined in some cases.

Some scripts that source stackrc use set -u, which will error
when unknown variables are accessed

config: get_meta_section() misunderstands the beginning of metasection

For example, the line, "if [[ -n $no_proxy ]]; then" is misparsed
as the beginning of metasection because get_meta_section() misses
escaping of "|" unlike get_meta_section_files().
This patch adds necessary escape as "|" -> "\|".

Fix the option of a2ensite command

devstack fails with trema when  execute
"sudo a2ensite sliceable_switch" command, without ".conf" filename extension
with Apache2.4, Apache2.22. With Apache 2.2, it successes.
Because in the versions which newer than version 2.2,
file checking of a2ensite command is more severe.
So, a2ensite command forbid "sliceable_switch" without "/conf".

Added ".conf" filename extension.

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.

Neutron: create network resources when agents are started

Creating network resources before the agents start with the ml2
plugin might result in bnding failures for some resources such as
DHCP ports because the resources are created before the agents
report to the server.

This patch should ensure all agents have started and reported
their state to the server before creating network resources.
