Kevin Carter e08c58dd15 modify fact gathering to use local facts
This change makes the retention gathering operation faster by storing
the retention values as "local facts". The local facts are then
referenced in templates loading from the local fact file instead of
running repetitive queries which are slow making very large deployments
cumbersome. To make the retention policy fact gathering process smarter
it will now automatically refresh if undefined or should the
elasticsearch cluster size change. This will ensure we're improving
speed of execution while also catering to the needs of deployers to
grow, or shrink, elasticsearch cluster sizes.

Documentation has been added regarding the new option and why it may be
of use to depoyers.
