[Fedora] Install dnsmasq on n-cpu less host

The libvirt-daemon-driver-network pulls the dnsmasq,
on hosts where the n-cpu installed with libvirt backend.

But nothing installs it if you have only n-net or q-dhcp,
on the given hosts.

dnsmasq-utils does not depends on dnsmasq,
because it can work with other local dhcp servers.

Support of an alternate pypi server

Currently pip will get the package from the https://pypi.python.org server.
For CI, it's a problem as Internet connection can be down,
the pypi server down, etc...

The usecase is for a company/user that maintain a local pypi mirror
and give the option to use this server instead of the official one

Don't try to regenerate existing ssl certificates

Rerunning stack.sh after some failure unrelated to ssl setup will fail
due to certificates already existing in the CA index. Don't regenerate
them instead. This is a workaround making devstack development easier
rather than something typical user would run into.

Do a proper tls/ca cleanup in unstack

Certificates and the index were left in the data directory after
running unstack. That would break devstack on the next run.

XenAPI: Use GUEST_PASSWORD when installing DomU

We know what the GUEST_PASSWORD will be, so set it during DomU
installation; therefore if the installation fails for any reason
we have a correct GUEST_PASSWORD set rather than the obscure and
undocumented 'r00tme'

XenAPI: Always add latest Cirros euc image

Some tests, such as test_minimum_basic_scenario, assume qcow and if
a qcow image does not exit, falls back to the euc image.
This change ensures these tests work in the stock XenServer environment.

Add SERVICE_TOKEN to the sample local.conf

I expect the sample local.conf file to contain all the required
variables. However, after copying samples/local.conf, the stack.sh
script still asks for SERVICE_TOKEN.

This commit adds the SERVICE_TOKEN definition to local.conf so that a
new user can just copy samples/local.conf, edit it, and have a running
stack.sh without the mild annoyance of having more variables to set.
