Make TLS and Authorization Configuration Fields Optional

[yorozunouchu]

This pull request fixes #565 where the TLSNotary server fails to start when specific configuration fields (private_key_pem_path, certificate_pem_path, and whitelist_csv_path) are missing, even when the corresponding features are disabled.

Please review and provide feedback!

Remember to base your PR on dev instead of main~

if the pem paths are not set when tls.enabled is true, we should throw an error — like your line 297

[yorozunouchu]

we have updated pr to be based on the dev branch instead of the main branch and added validation to throw an error when TLS is enabled but PEM paths are not set.

@yorozunouchu i didn't see the error throwing fix yet, have you guys pushed it? right now if paths are not set it's still returning None, but we need it to throw error — so instead of doing if let Some(path)... just directly do something like path.ok_or_else(...)?
