RANGER-5529: RangerAuthorizer update to be REST friendly

[mneethiraj]

What changes were proposed in this pull request?

• updated RangerAuthorizer.getResourcePermissions() to replace multiple parameters with a single parameter, to make it HTTP POST friendly
• restricted the visibility of class RangerAuthzPlugin to package level, since this is not meant for use outside this package

Though this is a breaking change since the previous release (2.8.0, release earlier this month), updating to the new method signature is trivial (enough to avoid having to carry the previous API version in all releases going forward).

How was this patch tested?

• verified all unit tests pass sucessfully

Pull request overview

Updates the Ranger authz API to make getResourcePermissions() REST/HTTP-POST friendly by wrapping inputs into a single request object, and adjusts embedded implementation/tests accordingly.

Changes:

• Replace getResourcePermissions(resource, context) with getResourcePermissions(RangerResourcePermissionsRequest) in the RangerAuthorizer API.
• Introduce RangerResourcePermissionsRequest model for REST-friendly request payloads.
• Update embedded authorizer/plugin and unit tests to use the new request wrapper; adjust RangerAuthzPlugin constructor visibility.
