Made offer constraints filter and protobuf non-optional inside the code.

Given that Mesos now provides a guarantee that specifying no offer
constraint in UPDATE_FRAMEWORK/SUBSCRIBE call is equivalent to
specifying default-constructed `OfferConstraints`, and that we are
intending to make the V0 scheduler driver always require offer
constraints as an argument to the `updateFramework()`, it no longer
makes sense to keep `OfferConstraints`/`OfferConstraintsFilter`
optional inside the Mesos code base.

This patch replaces a non-set `Option<OfferConstraints>` with
default-constructed `OfferConstraints`, and a non-set
`Option<OfferConstraintsFilter>` with a default-constructed filter.
