* adding in serialization of requests

* code cleanup

* adding some happy path tests and fixing mock

* mock still broken

* fixing linting

* updating name on proto

* missed naming

* placeholder fix for TestClient_HTTP

* removing duplicate change log

* adding in test for get payloadv4 as well as some tests

* added tests for execution client testing, fixed encode type

* adding comment for placeholder test

* fixing test and addressing feedback

* feedback

* flipping the test names, was used in reverse

* feedback from kasey

* reverting switch back to if statements to fix bug
