Have public API endpoints for pipelines runners

Currently Bitbucket pipelines only offers public API endpoints for pipelines: 

https://developer.atlassian.com/bitbucket/api/2/reference/resource/repositories/%7Bworkspace%7D/%7Brepo_slug%7D/pipelines

As a customer we would like to request similar public endpoint for the pipelines runners.

With the following requirements:

• manage global workspace/repository runner config, as we as per runner config over-rides
• get status summary for runners - i.e. details of runners that are running, idle, and their last activity timestamp, etc.
• get list of queued steps for all sets of labels
• get the download link to the latest runner version (Linux shell, MacOS and Windows runners)
