Newly introduced attr - SAI_MIRROR_SESSION_ATTR_GUARANTEE_RATE is in packet-rate threshold(pps) and existing SAI_MIRROR_SESSION_ATTR_SAMPLE_RATE statistical sampling (1:N statistical ratio) - Since these attribute operate in different domain - can you define the interaction semantics in this proposal.

*
* While guarantee rate is not breached, all packets will be sampled (100% sampling).
* Once breached, packets will be sampled based on the mirror statistics (fallback to
* statistical sampling based on SAI_MIRROR_SESSION_ATTR_SAMPLE_RATE).
*
* This is expected to enable guaranteed sampling for very low pps flows.
* A value of 0 disables the guarantee rate feature.

* @type sai_uint64_t
* @flags CREATE_AND_SET
