WithMaxSendBufferSize sets the maximum size of the send buffer. When the
send buffer is full, for example due to errors in the transport, the server
disconnects the corresponding client.
The maximum buffer size should be large enough to accommodate the burst of
peer change notifications than happens on an initial call where all nodes in
the cluster are notified as being added.
WithoutTLSInfo configures the service to send peer change notifications
without TLS information. This implies that TLS is disabled for the Hubble
gRPC service.
