Enable to pass APIFY_TOKEN as a parameter or enviroment variable

[JJetmar]

It was mentioned in #702 (comment) and I basically ran into the same today.

wanted to use apify-cli for one-time apify run under specific user without a need to do extra logins.

I blindly tried something like:

my@localhost:~/Projects/my-actor> APIFY_TOKEN=MY_APIFY_TOKEN apify info

username: loggedInUserName
userId: loggedInUserId

but it returns the logged-in user instead of the one from passed APIFY_TOKEN. Based on the previous mention I expect it is not currently possible.

I am opening this issue to discuss/track this feature request.
