Refactoring auth init and adding tests

[cbb330]

Summary

problem: 1) auth requirement is not documented in swagger UI 2) auth interceptor init is not tested

(for context, this PR is from a ticket that is meant for me to onboard to the team and learn the code. as part of skilling up I've used refactoring to learn the code better. also, a lot of this code was made in an attempt to add custom headers as types exposed in our client SDK which turned out to be more complexity than it is worth.)

changes:

• refactored client codegen shell scripts to use a parameterized openapi-codegen cli, unblocking version upgrade (bumped version to 6.6.0
• logic for converting from clusterproperties yaml -> java objects is pulled out from TablesMvc and into its own util class for testability, refactored for readability.
• • along with move and refactoring, 3 unittests to prevent regression
• SwaggerConfig.java deleted and merged into TablesMvcConfigurer to both reduce # of places to look for config as well as utilize shared initialization steps. swagger will now init with security documented in UI if security is declared in cluster properties.
• Authorization is now required in e2e/h2/* tests which enables testing that the springboot app initializes properly with auth interceptor. new unittests for this
• Automocked MVC will now include Authorization header by default, enabling unittests to use auth required endpoints and without any extra configuration
• moved AuthorizationPropertiesInitializer to be used in either h2 or mock locations. small unittest for this too
• AuthorizationPropertiesInitializer now also defines auth interceptor

still TODO:

• fix naming of getCons (handlerinterceptor class loader)
• unittest the new HandlerLoader logic
• add documentation in this PR
• investigate whether front end docs + back end validation can be consolidated further
