Fix install_ceilometer and install_ceilometerclient

Other projects do a setup_develop in install_*. This standard is used by
grenade to do installations. Currently grenade uses install ceilometer
as part of the upgrade script, but this doesn't actually install the new
ceilometer.

Remove output filter on rabbitmq install

The original workaround was for an init script that grabbed stdout.
This was some time ago and I think it's safe to remove.

It can be a problem on Fedora; out-of-the-box some old F20 images can
have a broken dependency when rabbitmq installs.  With this in place,
all helpful output goes into the temp log file, but it is never shown
because the install_packages function exits the script.  Thus things
just stop and you have no idea why.
