             Summary: Introduce agent attributes that require frameworks to 
"opt-in" for offers.
                 Key: MESOS-8785
             Project: Mesos
          Issue Type: Epic
          Components: agent, allocation, master, scheduler api
            Reporter: Benjamin Mahler

In the past we have had cases of special agents (e.g. nodes with gpu, nodes 
with non-default region) where we've added one off opt-in behavior for getting 
offers from those nodes. This opt-in behavior for getting resources from these 
agents has been based on framework capabilities (e.g. GPU_RESOURCES, 
REGION_AWARE), however a generalized mechanism based on attributes would be 
useful for future cases.

An "opt-in" agent attribute means that the framework has to opt-in its role(s) 
to specific opt-in attributes in order to obtain resources from agents that 
have the attribute.

For example, we have a cluster with 5 gpu nodes and want to ensure that these 
are used for only gpu workloads. The operator would tag these machines with a 
"gpu_workload" attribute and mark this attribute as opt-in. Now, only those 
roles that frameworks opt-in to the "gpu_workload" attribute will receive 
offers for these agents.
