[dashboard] does not create the apache site properly on centos

[Darren Birkett]

On centos, the cookbook drops the following file:

/etc/httpd/conf.d/openstack-dashboard

However, the main httpd.conf includes the following:

Include /etc/httpd/conf.d/*.conf

So, it's not getting picked up because of the lack of .conf extension.

We have two options to fix:

1) ensure file is created with correct extension on centos/rhel
2) use same a2ensite/a2dissite methods that we use on ubuntu. The sites-enabled/sites-disabled directory hierarchy is supported on current versions of centos/rhel (>=6.4 I think).

I prefer the latter as it is better code reusability and less maintenance.

    creates openstack-dashboard site properly on centos/rhel

    Fixes: bug #1271193
    Implements: blueprint centos-rhel-for-dashboard

    On centos/rhel we now support the sites-enabled/sites-available style
    confs. This patch moves to use this approach on centos/rhel. It also
    fixes the above bug which was causing the site not to get loaded
    properly because it did not have the .conf extension. Also remove the
    rhel/centos specific tests for the openstack-dashboard site since
    rhel/centos now behaves the same as ubuntu in this regard.

    Note I am purposely ignoring fedora/others in this patch since the level
    of support for those is still tbd.
