Allow mongod service to launch on Fedora

Fixes bug 1144907

Previously, the mongod service may fail to launch, if the eager
filesystem freespace check trips over an SELinux AVC or finds
a lack of freespace (depending on the up-to-datedness of the
selinux-policy-targeted package and the disk size/usage in the
hosting instance).

We work around these issues by ensuring the selinux-policy-targeted
package is up-to-date when ceilometer is enabled on Fedora, and
also setting the --smallfiles option.

Quantum: use generic VIF driver

For plugins that support VIF bindings, make use of the
LibvirtGenericVIFDriver libvirt vif driver. The plugin
returns the VIF type to Nova which inturn "knows" what
to do.

Don't directly pip install tempest pip-requires

This code:

    # Tempest doesn't satisfy its dependencies on its own, so
    # install them here instead.
    pip_install -r $TEMPEST_DIR/tools/pip-requires

causes us to do:

    Found existing installation: oslo.config 1.1.0
     Uninstalling oslo.config:

so rather than 1.1.0 installed, we end up with 1.1.0b1 and everything
goes kabloomy.

It looks like this comment came from a time (commit 9a352daf) before
tempest included proper install_requires (tempest commit 5abb253c3).

It should be safe to delete this and allow setup_develop() do all the
work just like the other projects.
