SERVICE-SCALE - A general requirement for service scale.

Note to team: When reviewing service scale requirements I found the absolute number to run counter to the compression intent.  I think a better alternative is to specify the requirement as below, leaving the absolute scale supported by a proposal to the analysis phase.

Description: A proposal SHOULD support larger number (hundreds of thousands) and smaller number (thousands) of services locally instantiated with relatively better compression for smaller service scale.

Rationale: Service scale can be directly related to SID length.  More services instantiated locally at a node requires more bits to encode the SID.  The maximum scale supported by a proposal can directly impact its ability to compress SR information.

Metric: A proposal that meets this requirement will support a large or small number of services with relatively better compression when fewer services are addressable.
