Use Hybrid::equal_to instead of Hybrid::equals
From #371 (closed) we get that we want to move to use Hybrid::equal_to
instead of Hybrid::equals
. To give some slack for people to move, we first introduce Hybrid::equal_to
in %DUNE 2.10.0 and later will deprecate .Hybrid::equals
in %DUNE 2.11.0
Closes #371 (closed)
