testify is used throughout the codebase; this switches mocks from gomock to testify with the help of mockery for code generation. Handlers and mocks in test/utils/oidc are moved to a new package: mockery operates package by package, and requires packages to build correctly; test/utils/oidc/testserver.go relies on the mocks and fails to build when they are removed. Moving the interface and mocks to a different package allows mockery to process that package without having to build testserver.go. Signed-off-by: Stephen Kitt <skitt@redhat.com>
