New KeyOperation, KeyOperationPolicy and builder concepts (#814) 

* Added new KeyOperation and KeyOperationBuilder concepts
Changed Jwk#getOperations and JwkBuilder#operations from methods that accepted and returned Strings to use new KeyOperation instances
Added Jwks.OP#builder() method to create a KeyOperationBuilder

* Changed Jwks.OP#WRAP to WRAP_KEY and UNWRAP to UNWRAP_KEY to match RFC names

* Added new KeyOperationPolicy and KeyOperationPolicyBuilder concepts
Added Jwks.OP#policy() builder method to create a KeyOperationPolicyBuilder
Added JwkBuilder#operationPolicy and JwkParserBuilder#operationPolicy methods for configuring custom KeyOperationPolicy instances during JWK building and parsing, respectively.
