BZ #1075818 - Create New Hostgroup to enable HA deployments.

https://bugzilla.redhat.com/show_bug.cgi?id=1075818

Adding memcached.
BZ #1064056 - Foreman Heat ports not opened

https://bugzilla.redhat.com/show_bug.cgi?id=1064056

Open ports on the controller node for Heat:

* 8000 for opehstack-heat-api-cfn
* 8003 for opehstack-heat-api-cloudwatch
* 8004 for openstack-heat-api

A new firewall rule has to be added, because if the ports would be
added to the existing one, the port count would be greater than the
maximum for iptables multiport extension (maximum is 15), and creating
the rule would fail with a message "iptables v1.4.7: too many ports
specified".

BZ #1064056 - Foreman Heat ports not opened
BZ #1053623 - openstack-selinux package not installed

https://bugzilla.redhat.com/show_bug.cgi?id=1053623

Package openstack-selinux is now installed on RHEL/CentOS nodes
running OpenStack services. It is not installed if the node runs
Fedora, because selinux-policy package on Fedora is being updated
more frequently and should not need additional rules.

Merge pull request #151 from jguiditta/ha_keystone_fixes

BZ #1082811 - HA Keystone improvements.
BZ #1082811 - HA Keystone improvements, cont'd.

https://bugzilla.redhat.com/show_bug.cgi?id=1082811

Tweaks.  Add and use the template for the bash script
/tmp/ha-all-in-one-util.bash that contains logic to assist with puppet
flow.  Simplify quickstack::pacemaker::rsync -- end result of waiting
for the non-vip servers to sync up is the same.
BZ #1073087 - [RFE] Use subscription-manager

https://bugzilla.redhat.com/show_bug.cgi?id=1073087

Use subscription-manager by default instead of rhnreg_ks to subscribe
the system for Red Hat repositories.

Only parameters for username/password registration are present by
default, but more subscription options are available (including the
original rhnreg_ks). Those parameters are commented out, not populated
by default, not to confuse users what params to fill in. (Creating a
parameter with an empty string as value is not allowed.)

This commit depends on Foreman having a redhat_register snippet that
supports subscription-manager and also has a workaround for correctly
enabling repositories on RHEL 6.4 [1].
