transport_tcp: add read and write deadline

[j-licht]

add read and write deadline for tcp transport, otherwise it takes a long time to detect offline devices.

I guess main issue could be now for client usage as you need to have this connection upfront.

I find this very hardcoded. Could maybe TCP keep alive solve problem?

With keepalive enabled I'm still seeing the sip request are blocking.
What do you think about having an WithOptionSetDeadline to configure that?

Hi @j-licht . Right now you can customize transports trhough TransportsConfig which can be passed through UA on TransportLayer.
What we basically need is to add those options somowhere in tcp transport.
On other hand, lib is moving right now to 1.0.0, and this may be delayed to 1.1.0
