Rsync and sql:sync with docker compose on remote server

[christianwiedemann]

Is your feature request related to a problem? Please describe.
Right now it is not possible to rsync and sql:sync files from a remote docker compose instance. (Or do I miss a configuration?)
In consolidation/site-process#85 I add support for docker host parameter which adds -H to docker compose and docker-compose. You can use rsync with rsync -e "docker -H ssh://user@host compose exec -i" to use rsync without ssh installed on a docker container with all features.

See
#6213

Please let me know if this PR has a chance to get merged! Thanks!

Describe the solution you'd like
Add rsync -e "docker -H ssh://user@host compose exec -i" support

Describe alternatives you've considered
I found no alternative but maybe I missed something.
