Make kubeval's directory recursion strategy similar to that of kubectl.

[debayande]

The suggestion

When pointed to a directory in order to validate its contents, could we please have kubeval:

• Process only the immediate children of the specified directory by default.
• Recursively process all children of the specified directory only when passed a parameter like --recursive.

This would also bring kubeval's behaviour in concordance with that of kubectl.

The rationale

I have a top level directory containing all the manifests that I'd like kubectl to apply. Within this directory is a subdirectory containing (Sops-)encrypted descriptions of ConfigMaps containing sensitive data¹. I'd like to be able to point kubeval to the top-level directory and have it validate its immediate children only rather than recurse down to the directory containing the descriptions of the ConfigMaps and report a failure.

Thank you.

¹ In my process I'm applying the descriptions of the ConfigMaps as a different step, which also decrypts them on the fly.
