Bitbucket API Integration during Pull Request Build to validate the changelogs and coding standard

This implements the Bitbucket API integration in pr (Pull Request) to validate changed files. It only fetches the change file and validates it against a list of the file maintained in core_files.txt

Pull request Build changes the status of the Pull request [approve/decline/change_requested] if the committed file is a part of core files and put the comments in Bitbucket Pull request.
