Officially support creating project in user namespace using `namespace_id` from user resources / data sources
This change set addresses #85 (closed). It implements the namespace_id
attribute on the gitlab_user
and gitlab_users
resource and data sources respectively.
It also adds a test and example for the gitlab_project
resource for creating a project in a users namespace given the namespace_id
from the former mentioned resources / data sources.
I've implemented this upstream in gitlab!82045 (merged) and will be available in GitLab 14.10, thus this PR is blocked until:
- GitLab 14.10 is out on 2022-04-22
- https://github.com/xanzy/go-gitlab/pull/1430 is merged
Closes: #85 (closed)
