using the CLI tool in github actions

[shmuel-blitz]

Hi
thanks for this great tool!

i kind of like the idea of using github actions to run the same scripts in the same way as it would run on my machine.
but i can't use the beanstalk-deploy CLI in the same way i use on my machine
because of this env var

can we export a CLI only version that will not use the "IS_GITHUB_ACTION" env var ?
or
add a neutral env var to negate it like EB_CLI_DEPLOY=true

if (IS_GITHUB_ACTION && !EB_CLI_DEPLOY) {
    // do the github actions magic
} else {
    // use normal CLI args
}

I'll be more than glad to do the PR if you like the idea
