* update db:schema due to migration

* Allow auto update packages in the development mode without building image

* add sidekiq support to docker-compose

* Pass sidekiq cofig file

* passed the env file in base image rather than separately in rails, web packer and sidekiq in docker-compose

* changed concurrency to finer values
* removed default size set in sidekiq redis config
* Added the sidekiq config option in Procfile.dev
