Add a workflow to update dependencies (#490)

* Add a workflow to update dependencies

* Use '--no-docker' to run dependency update using local pythons

Default method is to use docker

* Only run the dependency update workflow manually

PR are only created for master

* Create constraints for all python versions

* Use manylinux2010_x86_64:latest to update dependencies
