Allow fetching descendant milestones in GraphQL API
What does this MR do?
When include_descendants
parameter is passed, also milestones
from all subgroups and subprojects are returned but only
if visible to user.
Database query
A query to get all milestones in `gitlab-org` group and all its subgroups and subprojects a user can see. Query plan (after warmup): https://explain.depesz.com/s/aWGD
