QoS overrides for meters/policers

Support for the QoS override feature on an access SAP allows the user to override the meter parameters, such as CBS, MBS, rate (CIR and PIR), mode, and adaptation rule (CIR and PIR) at the SAP context.

When meter parameter values are not overridden, the values are taken from the SAP ingress policy. That is, QoS override is not used.

Meter override commands are supported on all types of access SAP.
