Memory quota

The memquota adapter can be used to support Istio’s quota management system. Although functional, this adapter is not intended for production use and is suited for local testing only. The reason for this limitation is that this adapter can only be used in meshes where there is a single instance of Mixer running for the whole mesh (i.e. non-HA configuration) and if that single instance crashes, all outstanding quota values will be lost.

This adapter supports the quota template.
