Redoc options

[DoooMer]

Thanks for useful tool. It would be nice to be able to set Redoc options from environment variables for example.

I see it like this:

docker run -d -e REDOC_OPTIONS="{hideLoading: true, nativeScrollbars: false}" ... volbrene/redoc

@DoooMer Nice Idea, I can take a look at it in a few days, shouldn't be a problem, i think.
