[Task]: [RRIO] [Test] Create test Caller and SetupTeardown interface implementations

[damondouglas]

What needs to happen?

The output of this task are definitions and implementations of the Caller and SetupTeardown interfaces:

interface Caller<RequestT, ResponseT, ApiErrorT extends ApiException> extends Serializable {
    ResponseT call(RequestT request) throws ApiErrorT;
}

interface SetupTeardown<ErrorT extends Exception> extends Serializable {
	void setup() extends ErrorT;
	void teardown() extends ErrorT;
}

Test implementations of Caller and SetupTeardown call the quota aware endpoint built and deployed from #28708 and #28709. Additionally, configurable mock implementations mimic response and error scenarios to supporting unit testing.

Measures of Ready

Work on this task depends on:

• [Task]: [RRIO] [Testing] Define and implement mock quota aware API #28708
• [Task]: [RRIO] [Testing] Deploy mock quota aware endpoint #28709

Measures of Done

This task is considered done when:

• Caller and SetupTeardown interfaces exist in the RRIO project
• Test implementations successfully call the deployed mock quota aware endpoint

Issue Priority

Priority: 2 (default / most normal work should be filed as P2)
