title: Creating a single bitbucket-pipelines.yml file for multiple projects
body: <p>I have a large number of microservices (40+) with identical pipeline requirements (currently very simple: build, test, deploy). Each of them lives in its own repository. Obviously, I would like to avoid having to change my bitbucket-pipelines.yml file in 40 places as we improve our pipeline. I know travis and gitlab both offer an import/include feature that allows you to include a 'master' yml file. Is there anything similar for Bitbucket Pipelines? If not, what alternatives are viable?</p>
  
  <p>Thanks!</p>
