> Currently, service interdependency are statically defined in the stack regardless its
needed or not.  For instance, Spark has a static dependency on Hive and will force Hive to
be installed whenever Spark is install, but Hive is only needed if Spark Thrift Server component
is installed.
> It would be nice if the stack has the ability to declare the dependency conditionally
and at component level and the dependency will only be in effect when the component is chosen.
