Review request for mesos and Benjamin Mahler.

Bugs: MESOS-9324

Repository: mesos

Description (updated)

The master flag min_allocatable_resources currently only supports
scalar resources. Sometimes it is desirable to control the quantities
of non-scalar resources in the offer as well, for example, to
ensure offers always contain port resources.

This patch extended the flag to cover non-scalar resources.
For RANGES and SET type resources, their quantities are the
number of different instances in the range or set. For example,
range:[1-5] has a quantity of 5 and set:{a,b} has a quantity of 2.

This patch also updated affected tests and modified the existing
test for min_allocatable_resources to cover the updated use cases.
