Add optional Cloudfront invalidation step at the end

[jgarth]

If $AWS_CF_DISTRIBUTION_ID is set, a Cloudfront invalidation request will
be created for paths /*. Useful when hosting websites with S3 + Cloudfront.

@jgarth It would be useful to validate not /*, but objects that were really changed.

That could be a really useful feature, but it could be optional.
Currently we have issues with implementing 100% bulletproof CSP with nonce, and it happens that Cloudfront do not have functionality to inject nonce to all script and style tags in html served, so we are thinking about other solutions that provides desired CSP nonce security. if somebody have non-PHP solutions, please share with me.

In addition to AWS_CF_DISTRIBUTION_ID, what if INVALIDATE_PATHS was also added? Perhaps 'index.html' could be a suitable default value.

Currently, I'm getting by with https://github.com/chetan/invalidate-cloudfront-action but it sure would be great to have everything under one roof, so to speak.

This would be awesome.
