Memory quota

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

This adapter supports the quota template.
