[services] Start/stop multiple services DEV-1270

[mikeland73]

Summary

This allows starting/stoping multiple services:

devbox services start starts all services
devbox services start s1 s2 starts s1 and s2

If a service fails to start/stop we print and error and continue. If only a single service is meant to be started/stoped we return an error.

How was it tested?

devbox services start
devbox services stop
devbox services start apacheHttpd php-fpm
devbox services stop apacheHttpd php-fpm

LGTM, but at some point I think we should invest in incorporating the process manager.

@loreto agreed, I really like https://github.com/F1bonacc1/process-compose but it will require some modifications to work the way we want.
