Statically-defined list of filters to apply on cluster config
property updates.

This will initially be used to filter out properties that do not
need to be set, due to a given dependency property not having
an expected value.

The UI uses the Recommendations/StackAdvisor APIs to accomplish this, but
Blueprints will use filters in the short-term, and hopefully move to a more
unified approach in the next release.

This filter approach will also be used to remove properties in a given component
that are not valid in a High-Availability deployment (example: HDFS NameNode HA).
