Remove Fedora/libvirt workaround

An updated libvirt package to address [1] is in Fedora 20 now, so we
don't need this work-around.  Modify the comments of the other part of
the work-around (restart of services) and link to the most relevant
bug

be a little more clever about interface default

the interface default of eth0 has become more wrong since we've
got a generation of Linux distros that don't use eth* as their
interface naming. Instead of that do a slightly more clever, but
probably still wrong thing, of picking an interface that exists
and is a physical interface.

This is still overridable, however won't cause really cryptic
failures in nova-compute because it's trying to use an interface
that doesn't exist *really* late in the network creation.

Fix the way Apache site configuration files are used, to improve OS portability

On Ubuntu 14.04, the site configuration file must have a .conf suffix for a2ensite and a2dissite to
recognise it. a2ensite and a2dissite ignore the .conf suffix used as parameter. The default sites'
files are 000-default.conf and default-ssl.conf.

On Ubuntu 12.04, the site configuration file may have any format, as long as it is in
/etc/apache2/sites-available/. a2ensite and a2dissite need the entire file name to work. The default
sites' files are default and default-ssl.

On Fedora, any file in /etc/httpd/conf.d/ whose name ends with .conf is enabled.

On RHEL and CentOS, things should hopefully work as in Fedora.

This change puts all distribution-related site configuration file name differences in lib/apache and
the other services gets the file name for its sites using the new exported function
apache_site_config_for <sitename>.

It also makes Fedora disabled sites use the .conf.disabled suffix instead of removing the .conf from
the file name.

The table below summarizes what should happen on each distribution:
+----------------------+--------------------+--------------------------+--------------------------+
| Distribution         | File name          | Site enabling command    | Site disabling command   |
+----------------------+--------------------+--------------------------+--------------------------+
| Ubuntu 12.04         | site               | a2ensite site            | a2dissite site           |
| Ubuntu 14.04         | site.conf          | a2ensite site            | a2dissite site           |
| Fedora, RHEL, CentOS | site.conf.disabled | mv site.conf{.disabled,} | mv site.conf{,.disabled} |

Remove copy of cinder.conf.sample file

Rather than continue to be bit by conf updates
from external sources, Cinder is going to join
the party and cease generation of the sample.conf
as part of the unit tests.

First step however is to not attempt to copy it
from cinder/etc/cinder in the devstack setup.

This just removes that cp operation, nothing
in that sample conf was modfied from defaults
so it wasn't really doing anything anyway.

be opinionated: only use get-pip.py

get-pip.py is now on a CDN, and is the prefered way to get pip.

Remove the default path of using pip tarballs from pypi and use
get-pip.py on from here on.

make get-pip.py download failures more clear

curl dying ends up being a really unclear failure condition, and
hard to fingerprint in the gate. We should make this much more
explicit when we die.

Also, don't trust the upstream filename, because all the rest of
our logic would break if it changes anyway.

Update setuptools to latest for .dist-info support

Support for .dist-info directories was added in setuptools 0.6.28.

At this moment, Ubuntu Precise 12.04 provides setuptools 0.6.24
which is too old for our needs.

Six is installed from wheel which uses the .dist-info directory.
For six to be found, we need to install setuptools >= 0.6.28.

Updating setuptools to the latest version using pip will provide use
the needed version to make six discoverable.

Update again and retry a failed package install

On ubuntu, if we run into an error installing the package, it can be
because of transient upstream errors with repo sync state. Although
retrying the update won't fix it all of the time, it's low cost enough
to be worth a try before we totally give up.

Don't set nova api/conductor workers since nova handles this

The changes to devstack to set nova api/conductor workers to 4 predated
commit 75c96a48fc7e5dfb59d8258142b01422f81b0253 to default the workers
equal to the number of CPUs, so this change just removes the hard-coding
from devstack and relies on nova's defaults for number of workers.
