The clustercheck service currently connects to mysql as root
to poll the state of the galera cluster.
Update the generated config to use clustercheck credentials.

The step is typically set with the hieradata setting an integer value:
{"step": 1}
However it would be useful for the value to be a string so that
substitutions are possible, for example:
{"step": "%{::step}"}
This change ensures the step parameter defaults to an integer by
calling Integer(hiera('step'))
This change was made by manually removing the undef defaults from
fluentd.pp, uchiwa.pp, and sensu.pp then bulk updating with:
find ./ -type f -print0 |xargs -0 sed -i "s/= hiera('step')/= Integer(hiera('step'))/"

In HA overcloud deployments, HAProxy makes use of a helper service
called "clustercheck", to check whether galera nodes are available for
serving traffic.
This change implements a dedicated profile for clustercheck, which was
originally part of the pacemaker mysql profile. The profile generates
the necessary configuration files for clustercheck and let heat
templates manage the associated container's lifecycle.
