**Why?**
Currently the IDE loads a merge request based on only the
`source_branch` name. This means it loads MR's from
forks that have the same branch name (not good).

- This required updating the BE API to accept `source_project_id`

Fixing single string values in the 'include:' keyword of gitlab-ci.yml validations

See merge request gitlab-org/gitlab-ce!26998

This fix is a followup to !24098 which introduced a validation of the
`include:` keyword of a gitlab-ci configuration file when triggered
from /ci/lint API calls.

However, there was a test case missing: the case of a single string as
value. I have added a test case for that which shows that the code was
not validating it correctly.

This commit fixes that to allow all `include:` valid inputs.

Replace comment by variable

See merge request gitlab-org/gitlab-ce!27007

Instead of having a comment describing what a specific value is,
better to have a variable with a meaningful name.

https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/26248 added
support for deduplicating FindCommit requests using Gitaly ref name
caching. However, not all endpoints were covered, and in one case the
Gitaly wrapper wasn't actually surrounding the serialization step. We
can safely cache ref names between FindCommit calls for #index and #show
endpoints for merge requests and pipelines. This can significantly
reduce the number of FindCommit requests.

Allow reactive caching to be used in services

See merge request gitlab-org/gitlab-ce!26839

Add support for defining a reactive_cache_worker_finder function

the calling object. This allows reactive caching to work with Services
where the object cannot be obtained from DB but a new object can be
initialized.
