Add a service to proxy calls to Prometheus API

See merge request gitlab-org/gitlab-ce!26840

- Also refactor the get and json_api_get methods so that the get method
can be reused by the new proxy method.
- The new proxy method makes no changes to the request to the prometheus
server and response from the prometheus server. This allows it to be
used as a proxy to the Prometheus server, hence the name.

CE Backport: Re-use MR tabs styles to Epic tabs

IDE fix MR detection from fork

See merge request gitlab-org/gitlab-ce!26986

**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`

Show error when namespace/svc account missing

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.

Improve the Review Apps documentation by using gitlab-rails console

See merge request gitlab-org/gitlab-ce!27006

**Why?**

Previously it managed this as an internal data property, but there
was extra complexity involved because the component doesn't have
all the information it needs (i.e. the `mouseOver` prop).

This is a good opportunity to colocate the data prop with the component
that has the information to change it (i.e. `file_row`) and let
`new_dropdown/index` receive this value as a prop.
