<install> CONF_NO_JBOSS* works again though deprecated

The changes to enable CONF_CARTRIDGES deprecated CONF_NO_JBOSS{EAP|EWS}.
But to make these continue to work the same way is pretty simple. Now if
these are set to true, the corresponding cartridges are removed from the
list to install.
<install> bug 1060235: put parse_cartridges in set_defaults

https://bugzilla.redhat.com/show_bug.cgi?id=1060235

parse_cartridges is now run as part of the initialization of parameters
which is done in set_defaults. That way the results are available to
every action, enabling oo-install to continue splitting the install into
multiple invocations without calling out parse_cartridges.
Revert "oo-install: Call parse_cartridges action"

This reverts commit 52b18114b9b551630b1b52f95252786ba675d750.
The fix should go in openshift.sh

openshift.ks: Optionally register with RHN/RHSM

configure_rhn_channels, configure_rhsm_channels: Only register with RHN or
RHSM if credentials are provided.

configure_rhsm_channels: Only attach to a pool if a pool id is provided,
and skip any pools that are already attached.

validate_preflight: Allow the installation to proceed even if the rhn or
rhsm installation method is being used without any credentials provided,
as long as the host is already registered, and also allow installation
to proceed with the rhsm method even if no pool id is provided as long
as the required repositories are already available and credentials are
not provided (providing credentials would imply that we should register,
and re-registering would remove the existing repositories).

These changes allow the user to register with RHN or RHSM before running
the script and then use the rhn or rhsm installation method to have the
installation script configure channels, priorities, and excludes and
validate the configuration.

This commit fixes bug 1056906.
