It discussed several times when started to look at it and Bill proposed to add
some cls environment.
Finally, it's sent. After this change PMR is created while connection to CoSes,
and it's eliminates ability to connect the same PMR to several CoSes (which may
arise questions...),
and maps PMR handle directly to physical rule. It greatly simplifies life for
implementors.

Packet match rule creation is modified to include source and destination
class of service. Removes the ability to add any class of service directly
with pktio. If a PMR needs to be applied at the pktio level the same
should be applied to default class of service.
Packet match rule destroy function is updated to removes the link between
the source and destination class of service.
