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.

of full window height.

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`
