Assertion does not match its error message and comments for QueryOptions.readTimeout method

[seungh0]

Hi there,
I noticed a discrepancy between the comments and error messages in the QueryOptions.ReadTimeout method and the actual behavior of the code.
I suggest allowing the code to accept 0 without raising an exception to handle disabling the timeout.

spring-data-cassandra/spring-data-cassandra/src/main/java/org/springframework/data/cassandra/core/cql/QueryOptions.java

Lines 540 to 556 in 100b267

	/**
	* Sets the request timeout. Overrides the default timeout.
	*
	* @param timeout the read timeout. Negative values are not allowed. If it is {@code 0}, the read timeout will be
	* disabled for this statement.
	* @return {@code this} {@link QueryOptionsBuilder}
	* @see com.datastax.oss.driver.api.core.cql.SimpleStatement#setTimeout(Duration)
	* @since 3.0
	*/
	public QueryOptionsBuilder timeout(Duration timeout) {
	Assert.isTrue(!timeout.isZero() && !timeout.isNegative(), "ReadTimeout must be greater than equal to zero");
	this.timeout = timeout;
	return this;
	}

I've also submitted a PR to address this. I would appreciate it if you could review it.

Thank you.

Good catch, I think we might have more places like that one. I'm going to have a look during the merge.
