Storage: Add dualwriter test mocks (#86243)
* WIP: add mocks for dual writer * Test dualwriter mode1 * Re-add non implementation errors * Use testify assert * Write tests for mode2. * Lint * Remove comment * Update pkg/apiserver/rest/dualwriter_mode2_test.go Co-authored-by: Arati R. <33031346+suntala@users.noreply.github.com> * [REVIEW improve readability and call fn legacy fn * [REVIEW] rename mocks and setupFns * [REVIEW add missing test case * [REVIEW] add test case with getting object from storage and not legacy * Add deleteCollection * Test deleteCollection * Rename file --------- Co-authored-by: Arati R. <33031346+suntala@users.noreply.github.com>
