This PR adds a new updatable discrete trust region. This builds on the the fixed-point discrete TR added in a previous PR. The new class SingleObjectiveTrustRegionDiscrete is similar in behaviour to SingleObjectiveTrustRegionBox, but for a discrete search space.
The mixed search spaces notebook and integ tests now use this class, instead of FixedPointTrustRegionDiscrete from the previous PR.
Fully backwards compatible: yes
