Move all Dockerfile samples to non-root user

Expected Behaviour

As an OpenFaaS end-user, I want to run all samples on my OpenFaaS cluster, even with the new non-root feature enabled.

Current Behaviour

this will very quickly get out of hand if we allow it, i realize we don't have principles written down anywhere but to date one of them has been that binaries 'just work' without having to do any configuration. currently a user must set FN_MAX_REQUEST_SIZE, FN_MAX_RESPONSE_SIZE -- neither of these should be required to run.

test case:

cd tests/fn-system-tests/
go test -v

this

If we override PHP_INI_SCAN_DIR then the "special php.ini" files will not be used.
Ie: https://github.com/brefphp/bref/blob/0.5.9/runtime/layers/fpm/php.ini

Hi,

I wanted to enable binary support on API gateway, but could not find the way to do it via component's inputs.

Is this something that you would consider adding in the future?

If so, I can try to add this feature. It doesn't look too complicated.

Thanks!

Is your feature request related to a problem? Please describe.

Currently both lambdas can only have the same arn role (if set). However it would be better to follow the same approach that there is for the name field

  roleArn:
      defaultLambda: arn
      apiLambda: arn

The reason I say this is because I wouldn't want to give the defaultLambda access to the database.
