adding a option to set COMPOSE_HTTP_TIMEOUT variable

[upsilon01]

I would like to add a option to override default COMPOSE_HTTP_TIMEOUT value(60)
by adding it before the docker-compose command:

COMPOSE_HTTP_TIMEOUT=120 docker-compose up -d ....

should I make a PR on it?

Yes, please.

It should be already possible to do using the env option. I just didn't find it documented in the actual docs (in contrast to cwd option and alike).
