[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

Fix Swift config for Ceilometer usage

Ceilometer filter was previously removed from the Swift
configuration to avoid useless Ceilometer logs in the Swift
ones. This was fixed by setting only warning log level for
this Ceilometer part of the pipeline to keep only important
ones.

Switch to Fedora-x86_64-20-20140618-sda

The heat-slow job using the Fedora-20 image as L2 guest, the
currently used version is affected by the heartbleed issue and
the Mb-Bios bug issue observed with emulation.

This version of the  Fedora cloud image uses the no_timer_check
kernel parameter, which solves the MP-Bios Bug issue.

The Image tested with ~3000 heat-slow job, without any issue.

Add libyaml-devel package dependancy

Without libyaml-devel package installed (on Fedora-20),
running ./stack throws:

  [. . .]
  build/temp.linux-x86_64-2.7/check_libyaml.c:2:18: fatal error: yaml.h:
  No such file or directory #include <yaml.h> ^ compilation terminated.

  libyaml is not found or a compiler error: forcing --without-libyaml
  [. . .]

Adding this dependency to files/rpms/general resolves it. Also added to
files/apts/general.

Do not clean docs directory

The docs/source has been introduced by change-id:
Ide5f7d980a294c7a9f8a3decaed0939f1c239934, but clean.sh try to clean
whole docs direcotry, which is not right.

Meanwhile, there are directories in FILES_TO_CLEAN variable, which means
rm -f will not work. We need to use rm -rf.

Do a proper tls/ca cleanup in unstack

Certificates and the index were left in the data directory after

fix trove image addition

the previous addition to trove was done in a way that it was not
possible to discover from nodepool. This fixes our ability to do
that, especially with non-default on services.

Avoid huge libvirtd.log files on Ubuntu hosts

The libvirt log filter settings match against the filename of
the libvirt source emitting the log message. Normally these
file names are relative to the source tree root, but in the
Ubuntu binary packages these have somehow ended up as absolute
filenames from the OS root. This means that a log filter of
'1:libvirt' which is only intended to match src/libvirt.c
will in fact match every single file. This caused enourmous
log files on Ubuntu hosts running the gate.

The fix is to use '1:libvirt.c' as a more specific filename
match, but we can't do this unconditionally because libvirt
>= 1.2.3 does not use filenames for log filter matching
anymore. So only change the match on Ubuntu hosts for now,
since that's where the original problem lies.

While doing this, also turn off the logging of object ref
and unref operations, since those pollute the logs with lots
of noise.
