> Enable stacks to inherit individual services with the same stack or across stacks.
> When creating a new version of a service definition, unchanged details and scripts need
to be copied from the previous version to the new version.  Any changes made to the resources
that have been copied need to be propagated to them. This can be tedious and time consuming
as well as lead to user error while copying the changes.  Currently, one version of a stack
can extend another version of the same stack and will inherit everything in the stack including
potentially unwanted content.  This work is to allow single services to be inherited/extended
as opposed to the entire stack.
