Subject: [PATCH] [IMP] web: allow to restrict operators in domain selector

The domain selector currently determined the list of available
operators according to field types (and used only a subset of
supported ones).
In some context, we might want to restrict this list of available
operators. Indeed, in client-evaluated domains, the "ilike" operator
cannot be used for example.
