CLI: Ability to propagate multiple environment variables on group level

Currently we can deploy group variables by defining them in check group under environmentVariables parameter. Unfortunately this requires us to hardcode their values here or pass them one by one when deploying (e.g. $ VAR1=1; VAR2=2; VAR3=3; checkly deploy).

It would be great if Checkly CLI could automatically read .env file and propagate variables into its process. Or it could simply accept --env-file flag as checkly test does.

Is something like this possible please? It would make integrating into CI much more convenient.
