StatusOr.equals() cannot compare Status instances

[panchenko]

StatusOr has been introduced in #11330
The implemented equals() method tries to compare value or status.
However, Status.equals() intentionally does not compare its fields.

grpc-java/api/src/main/java/io/grpc/Status.java

Lines 654 to 660 in ca4819a

	* Equality on Statuses is not well defined. Instead, do comparison based on their Code with
	* {@link #getCode}. The description and cause of the Status are unlikely to be stable, and
	* additional fields may be added to Status in the future.
	*/
	@Override
	public boolean equals(Object obj) {
	return super.equals(obj);

The corresponding StatusOr test compares same Status instance and passes

grpc-java/api/src/test/java/io/grpc/StatusOrTest.java

Lines 62 to 63 in ca4819a

	public void equals_sameStatuses() {
	assertThat(StatusOr.fromStatus(Status.ABORTED)).isEqualTo(StatusOr.fromStatus(Status.ABORTED));

but would fail if there is a description

String msg = "1";
assertThat(StatusOr.fromStatus(Status.ABORTED.withDescription(msg)))
    .isEqualTo(StatusOr.fromStatus(Status.ABORTED.withDescription(msg)));
