Make broker segment unavailable exception configurable on Pinot Java client

[dang-stripe]

We're currently using the pinot java client for queries. With the introduction of #7397, we're seeing more query exceptions since the java client currently raises an exception when there are any exceptions in the response:

pinot/pinot-clients/pinot-java-client/src/main/java/org/apache/pinot/client/Connection.java

Lines 126 to 128 in 6611ff8

	if (response.hasExceptions()) {
	throw new PinotClientException("Query had processing exceptions: \n" + response.getExceptions());
	}

Can we make this behavior configurable on the client?

2 options I can think of:

1. Add a flag to not fail the query, but log the exceptions as response metadata
2. Configure certain error codes to be ignored

@Jackie-Jiang @xiangfu0 I think we have a preference for option 1 since it'll give us more control over what consistency guarantees we need which vary per query.

Agreed, here we should provide some options for client side to config when to fail and how the exceptions are thrown.

Thanks for addressing this! The fix is much appreciated.
