Enable debug logging in q-agt output

when only q-agt is used, without q-svc, typically in a multi-host config, q-agt wasn't logging debug output.
This change enable debug output, as it's done for q-l3, q-dhcp or q-meta agent.

Summary:

1. Starting with fedora 18 the httpd.conf has
    <Directory />
        AllowOverride none
        Require all denied

  which requires you to explicitly permit access to web content
  directories in other <Directory> blocks

2. Install nodejs on fedora 18 and above

Add a generic post-prereq phase

This generic extra phase is handy for fixing up things like python
modules after pip is installed or other distro specific requirements.

Fix attach volume detect in euca test

Fixes test for detecting when a volume has been successfully
attached to an instance to not just rely on the state being
in-use, but also be marked as "attached". The attachment
state will be displayed when https://review.openstack.org/#/c/27098/
goes through. The attachment state is not currently displayed
by euca-describe-volumes because of the extraneous data returned
by the API as per bug #1074901.

In the meantime the "attaching" status of the volume itself, rather
than the attachment state, suffices for the test to work properly, but in the long
term this will disappear as it is not a valid ec2 API state and
volumes will move straight to the in-use state.

Fixes bug #1170548

Add support for GlusterFS Cinder driver

The GlusterFS volume driver can be used with Cinder by setting the
following in localrc:

CINDER_DRIVER=glusterfs
CINDER_GLUSTERFS_SHARES="127.0.0.1:/vol1;127.0.0.1:/vol2"

Shares are <host>:<volume> and separated by semicolons.

Modify RPM lists for RHEL6

Modifications to the RPM list to make devstack work on RHEL6.  Makes
various packages only install on Fedora distros; generally letting pip
install the missing dependencies on RHEL.

Additionally the Qpid package name is different in RHEL6 to Fedora.
Also a small re-write of the config file is required to avoid
authenication issues.
