Change environment variable name

[gustavoggs]

I am using this in a project where we have different services that we connect.

My suggestion is to change the environment variable name from PROJECT_ID to GOOGLE_PROJECT_ID.

What do you think?

@gustavoggs Not sure I'd wanna change this, especially for people already using it. It seems very specific to your problem. Maybe for the different services you use, SERVICE_ID can be used instead? Seems more in line with the terms you're using like service.

It is not generating any conflict right now, but having only PROJECT_ID in the environment variables does not make it clear where this is being used, looks more like a project defined variable than a service defined variable.

Hmmm Not a bad idea. Let's add it in a new breaking release. We have some ideas about other refactoring of the library to make things more generic. I think being very explicit can't hurt. @gustavoggs

Could we make something like take GOOGLE_PROJECT_ID first, and then if there is nothing check PROJECT_ID? So that we don't break anything. I will take a look to this.
