<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
Update DNS key sig algorithm to SHA256.

Added configuration options to pass in the key algorityhm and size.

Defaults are:
CONF_BIND_KEYALGORITHM=HMAC-SHA256
CONF_BIND_KEYSIZE=256
Merge pull request #292 from calfonso/enterprise-2.0

Update DNS key sig algorithm to SHA256.
Merge pull request #288 from sosiouxme/installer-parse_cartridges-placement

Call parse_cartridges in set_defaults and not in do_all_actions or as an explicit action in the oo-install invocation.

Enable CONF_NO_JBOSS* to be used as before, though deprecated.
