cmd_button should allow to set env variables

[fabriziopandini]

Describe the Feature You Want

I would like to pass env variables to cmd_button, as I can do with local_resource

Current Behavior

cmd_button doesn't have an env argument

Why Do You Want This?

To pass env variables to the command defined in cmd_button without messing up os env variables

thanks for the request! shouldn't be too hard to add. the api exists on Cmd, just needs to get passed through the extension code that creates the Cmd:

https://api.tilt.dev/core/cmd-v1alpha1.html
