Description

mesos-execute cannot be used to run tasks on reserved resources, e.g., and invocation

$ mesos-execute \
    --resources=disk(some/role):32;cpus:0.1;mem:32 \
    --command=true \
    --name=<NAME> \
    --role=some/role \
    --master=<MASTER>

will not be able to use disk resources reserved to some/role.

This is due to the way mesos-execute performs its offer matching, e.g., as of 9af920c75d1

if (!launched && offered.toUnreserved().contains(requiredResources)) {

Any reservations are stripped from offers before matching against the required resources.

We should update mesos-execute so it can make use of reserved resources.
