# Which Problems Are Solved
This PR fixes the self-management of users for metadata and own removal
and improves the corresponding permission checks.
While looking into the problems, I also noticed that there's a bug in
the metadata mapping when using `api.metadata.push` in actions v1 and
that re-adding a previously existing key after its removal was not
possible.
# How the Problems Are Solved
- Added a parameter `allowSelfManagement` to checkPermissionOnUser to
not require a permission if a user is changing its own data.
- Updated use of `NewPermissionCheckUserWrite` including prevention of
self-management for metadata.
- Pass permission check to the command side (for metadata functions) to
allow it implicitly for login v1 and actions v1.
- Use of json.Marshal for the metadata mapping (as with
`AppendMetadata`)
- Check the metadata state when comparing the value.
# Additional Changes
- added a variadic `roles` parameter to the `CreateOrgMembership`
integration test helper function to allow defining specific roles.
# Additional Context
- noted internally while testing v4.1.x
- requires backport to v4.x
- closes https://github.com/zitadel/zitadel/issues/10470
- relates to https://github.com/zitadel/zitadel/pull/10426

# Which Problems Are Solved
Currently, users can't delete themselves using the V2 RemoveUser API
because of the redunant API middleware permission check.
On main, using a machine user PAT to delete the same machine user:
```bash
grpcurl -plaintext -H "Authorization: Bearer ${ZITADEL_ACCESS_TOKEN}" -d '{"userId": "318838604669387137"}' localhost:8080 zitadel.user.v2.UserService.DeleteUser
ERROR:
Code: NotFound
Message: membership not found (AUTHZ-cdgFk)
Details:
1) {
"@type": "type.googleapis.com/zitadel.v1.ErrorDetail",
"id": "AUTHZ-cdgFk",
"message": "membership not found"
}
```
Same on this PRs branch:
```bash
grpcurl -plaintext -H "Authorization: Bearer ${ZITADEL_ACCESS_TOKEN}" -d '{"userId": "318838604669387137"}' localhost:8080 zitadel.user.v2.UserService.DeleteUser

}
}
```
Repeated call
```bash
grpcurl -plaintext -H "Authorization: Bearer ${ZITADEL_ACCESS_TOKEN}" -d '{"userId": "318838604669387137"}' localhost:8080 zitadel.user.v2.UserService.DeleteUser

}
```
# How the Problems Are Solved
The middleware permission check is disabled and the
domain.PermissionCheck is used exclusively.
# Additional Changes
A new type command.PermissionCheck allows to optionally accept a
permission check for commands, so APIs with middleware permission checks
can omit redundant permission checks by passing nil while APIs without
middleware permission checks can pass one to the command.
# Additional Context
This is a subtask of #9763
