Execution API Electra: requests as a sidecar (#14492)

* wip * gaz * rename field * sammy review * updating execution api request and reverting response back * fixing linting * changelog * changelog * 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 * lint
