This adds a number of missing fields from the response.

In https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/9661, we
removed the `subscribed` field from API endpoints that needed to return
a list of issues or merge requests when to avoid full Markdown
processing.

However, we introduced a performance regression in GitLab 11.10
(https://gitlab.com/gitlab-org/gitlab-foss/merge_requests/26367) when we
converted `MergeRequestBasic` to `MergeRequest` in order to expose the
head pipeline in the
/api/:version/projects/:id/issues/:issue_iid/related_merge_requests
endpoint.

To avoid this overhead, we now omit the `subscribed` field in this API
endpoint.

Fix error when displaying pod logs of pod that has multiple containers

See merge request gitlab-org/gitlab!16236

- When a pod contains more than one container, the container name has
to be included in the pod_logs API call otherwise the Kubernetes API
returns 400.
- Also allow our logs API to take a container_name param which can be
used to choose which container's logs should be returned.

Avoid unnecessary locks on internal_ids

See merge request gitlab-org/gitlab!17123

This avoid an unnecessary FOR UPDATE lock on internal id records when
the iid value has been generated internally anyways.

The lock is still required to track any values that come in through
other means, i.e. set by a user (through the API).
