Currently package updates won't occur on a single node
non-HA pacemaker managed Controller because stopping
the node loses the quorum of 1.
This change gets the count of current nodes in the cluster and
if the count is 1 then specify --force when doing a pcs cluster stop.

This change adds alternative logic for handling package updates
on a pacemaker managed node.
"yum list updates" is now run and this script exits early if
there are no packages to update.
If the pacemaker service is not running then the previous puppet
logic remains, so a package update is performed which excludes packages
managed by puppet, and a flag is set to indicate that puppet should
perform an ensure=>latest on all packages it manages.
However if the pacemaker service is running, the following occurs:
- pcs cluster stop is run for this node
- a full yum update is performed
- pcs cluster start is run for this node
- pcs status is run until the hostname for this node appears in the
Online list
This means that puppet is not involved in the package update process when
the node is managed by pacemaker.

This change updates yum_update.sh so that we set set a boolean
output when "managed" packages should get updated. The
output is named 'update_managed_packages' and for the
puppet implementation it is wired up so that it
directly sets tripleo::packages::enable_upgrade to
control whether packages are updated.
It also modifies yum_update.sh to build a yum update excludes list for
packages managed by puppet. The exclude lists are being
generated via puppet-tripleo as well via the new 'write_package_names'
function that is now wired into all the role manifests.
This change does not actually trigger the puppet apply. The fix for
Related-Bug: #1463092 will be used to trigger the puppet run when the
hiera changes. As a minor tweak to this logic we append the
UpdateIdentifier to the config_identifier so that we ensure
puppet gets executed on an update where other (non-related)
hiera changes also occur.

This change adds config and deployment resources to trigger package
updates on nodes. The deployments are triggered by doing a stack-update
and setting one of the parameters to a unique value.
The intent is that rolling update will be controlled by setting
breakpoints on all of the UpdateDeployment resources inside the
role resource groups.
