Add a new parameter to enable/disable bootstrap

This change introduces a new parameter to enable/disable bootstrap
command by the keystone::bootstrap command. This parameter is useful
expecially in the deployment with multiple controller nodes, and we
can run bootstrap command on only one of the controller nodes while
we generate puppet.conf on all controller nodes, so that we can use
openstack providers in all controller nodes.
