BoundingRegion: Tolerance argument in the methods

Comes from this PR comment.

BoundingRegion api doesn't know about tolerance. In the first implementation that we have, BoundingBox asks for tolerance in its constructor.

Question is, would it be better to request tolerance only in the methods? This will imply recognizing from the BoundingRegion's api that tolerance is requested when calling the methods.

Probably the most related use-case is that this package in general, maliput will be used and when objects are being constructed there won't be possible to call maliput::api::RoadGeometry::linear_tolerance() in order to match tolerances, as probably the RoadNetwork won't be ready to be queried yet.
