[docs] [issue38178] Remove explicit "loop" argument from EchoClientProtocol example

[Hrvoje Nikšić]

New submission from Hrvoje Nikšić <hniksic at gmail.com>:

The EchoClientProtocol example receives a "loop" argument, which is not used at all in the TCP example, and is used to create a future in the UDP example. In modern asyncio code the explicit loop arguments are no longer used since the loop can always be obtained with get_running_loop().

The proposed patch makes the UDP example consistent with the TCP one (by having the constructor accept the on_con_lost future) and removes the loop argument from both.
