Description

This epic tracks work for implementing offer constraints for the scheduler API, i.e. an interface for frameworks to specify constraints on agent attributes in offers.

By specifying offer constraints, a "picky" framework can greatly reduce a time needed to get a suitable offer, especially in the case when the corresponding role is close to be out of quota.

One example which receives a huge benefit from offer constraints is running a "daemon set": when a framework needs to launch a task on every node of a large cluster, but the quota is just enough for all these tasks.
