Add OpenSIPS-CLI based healthcheck (#24)

* add healthcheck

* Update Dockerfile

* github: add docker push readme action

* docker-publish: bump login-action to v3

* Add build in opensips-publish

* quote extra modules

* add support for using a particular apt component

This provides a more flexible component, rather than hardcoded version+build

* github: fix opensips modules quoting

* github: change quotes

* Make healthcheck to depend on CLI arg
