Enables or disables long-polling support. By default, long-polling support is enabled with
the max timeout of {@value #DEFAULT_LONG_POLLING_TIMEOUT_SECONDS} seconds and
the jitter rate of {@value #DEFAULT_LONG_POLLING_TIMEOUT_JITTER_RATE}.

@param maxLongPollingTimeout A positive maximum allowed timeout value which is specified by a client
                             in the {@code "prefer: wait=<n>"} request header.
                             Specify {@code 0} to disable long-polling support.
@return {@code this}
