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.

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.

Implement Ceph backend for Glance / Cinder / Nova

The new lib installs a full Ceph cluster. It can be managed
by the service init scripts. Ceph can also be installed in
standalone without any other components.
This implementation adds the auto-configuration for
the following services with Ceph:

* Glance
* Cinder
* Cinder backup
* Nova

Note: only works on Ubuntu Trusty, Fedora 19/20 or later.
