#1 timeout for session not propogated to sendCmd

[Nikhil Sama]

On high delay/jitter paths, one might want to increase
the time out of session and sendCmd. The library
provides for a way to do this via the '-timeout' directive.

However, when session is called with a -timeout
argument, the library calls [ for Cisco IOS ] 'terminal
length 0' and 'terminal no editing' commands without the
given timeout argument. This defeats the purpose of
having a "higher timeout" for session since this part of it
will fail on a high delay path no matter what the timeout.
