Eric Hagan 57777ef79a Adds support for Pioneer AVR interface port number (#3878) ...

* Adds support for Pioneer AVR interface port number

https://community.home-assistant.io/t/support-for-pioneer-avr/503
telnetlib supports a port number so adding port as
an optional config element with a default of 23 resolves this.

* Adds timeout to Pioneer AVR

timeout in telnetlib defaults to socket._GLOBAL_DEFAULT_TIMEOUT
which is not a value, but rather a bare Object used for comparison.

telnetlib says the following about the timeout optional argument:
"The optional timeout parameter specifies a timeout in seconds
 for blocking operations like the connection attempt (if not
 specified, the global default timeout setting will be used)."

From the documentation for sockets:
"Sockets are by default always created in blocking mode"

Catching connect and timeout errors, logging to debug
and continuing.

* Catches timeout exceptions, logs and continues.
