Use $() instead of ``

There are other instances of this in other files, just tidying
ceilometer at the moment.

XenAPI: Add exit point after JEOS installation

If the user only want to run the installation of Ubuntu - to export the
template as an xva, it just needs to specify a non-empty value for:

EXIT_AFTER_JEOS_INSTALLATION

And the script will exit after the jeos template has been created.

XenAPI: Fix vimrc

DevStack installs a default minimal .vimrc file for the stack user.
Unfortunately the `syntax on` config line is not recognised by the vim
installed in DomU. It results in an annoying message being displayed
whenever the user is using vi. To avoid this issue, removing the `syntax
on` line.

XenAPI: Always update apt sources

If an appliance is used as a base OS, the user might want to use that in
a different region. With this change we always update the used mirrors
in the template.

Allow multi-line config items in meta-section of local.conf

It would behave such as the contents from each meta-section in
local.conf is copied to the destination files. One exception is the multiline
options not grouped together. In that case, the contents will be grouped
together in its destination config file.

Check tests/test_config.sh for examples.

This was originally committed in https://review.openstack.org/128805.
But the original change used AWK syntax that is not supported in AWK
3.1.8, and caused syntax error on servers with that AWK version. This
patch makes the necessary change so that it's compatible with AWK
3.1.8.

Compile Horizon message catalogs during stack.sh

Recently compiled message catalogs (mo files) were removed
in Horizon and django_openstack_auth repositories.
We need to compile message catalogs to make translations
available for Horizon users. It is useful for developers too.

Allow use of ceilometer agent coordination

Juno brings tooz-based coordination of ceilometer central, compute
and alarm agents. If CEILOMETER_COORDINATION_URL is set it will be
used as the value for a tooz coordination backend. If memcached is
chosen, its package will be installed. Other backends, such as
zookeeper can be configured, but installation is left as an exercise
for the devstacker.

In the default devstack setup having coordination will do little as
there are only one of each agent, but this makes it a bit easier for
multi-node or multi-agent setups.
