Respect timeout option when getting debugger port

[Fatme]

Sometimes when debug command is executed, an error is thrown because {N} CLI is not able to get debugger's port from device's logs. Currently {N} CLI tries 10 times (the retryCount) to get the port every 500 miliseconds. If the port is not found, an error is thrown. This PR calculates the retry count based on timeout option.
In case no timeout option is specified {N} CLI will try 20 times to get the port (this is the difference with the current behaviour).
In case when calculated retry count is lower then 10, {N} CLI will try 10 times to get the port.
