Issue #2289279: Initial commit for Drupal comments to disqus migration. Created destination plugin.
Removed duplicated function disqus_api(). Injected config.factory, logger.factory and entity.manager services. And few other minor fixes
Removed entity_id and entity_type fields from destination plugin instead directly using disqus-identifier field and relying on the migration process for preprocessing this field. Included API call for creating a disqus thread when it doesnt exists for the current comment migration.
Disqus needs both author_name and author_email parameters to post guest/anonymous comments. In case if either is not specified, posting such comments as site moderator's comments using the API
