fix(projections): add member (#2699)

* refactor(domain): add user type

* fix(projections): start with login names

* fix(login_policy): correct handling of user domain claimed event

* fix(projections): add members

* refactor: simplify member projections

* add migration for members

* add metadata to member projections

* refactor: login name projection

* fix: set correct suffixes on login name projections

* test(projections): login name reduces

* fix: correct cols in reduce member

* test(projections): org, iam, project members

* member additional cols and conds as opt,
add project grant members

* fix(migration): members

* fix(migration): correct database name

* migration version

* migs

* better naming for member cond and col

* split project and project grant members
