Currently we set 4096 as maximum for number of stream connections that we accept. However maximum number of file descriptors that systemd is willing to accept from us is just 1024. This means we can't retain all stream connections that we accepted. Hence bump the limit of fds in a unit file so that systemd holds open all stream fds while we are restarted. New limit is set to 4224 (4096 + 128).
