\Drupal\strata\Plugin\views\filter EnumFilter

Filters on a stored enum value, offering only the values that exist.

A string filter on the realm column asks an operator to type keyvalue and get it right. This offers the set instead, labelled, which is both easier and impossible to typo - and the set comes from the enum itself, so a realm added in a later release appears here without anything being updated.

There is a subclass per column rather than one filter for all four because ViewsFilter is not a repeatable attribute, so a plugin id needs a class of its own.
