Remove lb_private_vip and lb_public_vip

This patch removes lb_private_vip and lib_public_vip and instead uses
controller_priv_floating_ip and controller_pub_floating_ip.
Use array for load balancer member names and addrs

Instead of using a string containing a comma separated list of names
and addresses for load balancer members, use an array. This patch also
renames the load balancer params from lb_member_names and
lb_member_addrs to backend_server_names and backend_server_addrs.
Add controller_admin_floating_ip to load balancer

This patch adds the controller_admin_floating_ip to the load_balancer
class. This is needed so that the load balancer will proxy traffic for
this address, just as with the controller_pub_floating_ip and
controller_priv_floating_ip.
Accept a parameter for dynamic number of Gluster ports
BZ #1054181 - Set OS description consistently, install LSB

OS descriptions are filled in by LSB, which relies on lsb_release (supplied by
redhat-lsb-core).  On RHEL, they usually contain the variant string "Server",
so also update the description we preset to match that supplied by lsb_release.
Added $controller_admin_host to support admin endpoints
Update controller parameter names

The controllers params now end with _host instead of _floating_ip.
BZ #1052408 - HA Mysql manifest: allow creation of neutron db user.

https://bugzilla.redhat.com/show_bug.cgi?id=1052408

Add parameters to allow (optionally) the creation of the neutron db
user and set its db password.  Also switch to str2bool_i
from str2bool.
Add case-insensitive str2bool function and use it

The source is taken from the original [1], but case-insensitivity flag
is added to the regexes used.

BZ #998599 - Add options for SSL support using files or FreeIPA

https://bugzilla.redhat.com/show_bug.cgi?id=998599

If ssl and freeipa are true then certificates are obtained using
certmonger.

If ssl is true and freeipa is false then the the mysql and qpid
certificates and keys need to be passed in as arguments.

Horizon is configured to use ssl on the public interface FQDN if
ssl is true.

Secure qpid and mysql with SSL for nova, keystone, glance,
ceilometer, cinder and heat.

The following Foreman hostgroups support SSL:

Compute (Neutron)
Compute (Nova Network)
Controller (Neutron)
Controller (Nova Network)
LVM Block Storage
Neutron Networker
