rename membership and adopt newtype pattern (#5320)

* rename membership

rename UserOrganization to Membership to clarify the relation
and prevent confusion whether something refers to a member(ship) or user

* use newtype pattern

* implement custom derive macro IdFromParam

* add UuidFromParam macro for UUIDs

* add macros to Docker build
