Fix for vppctl and interactive commands (VPP-1038)
- Interactive commands like "ping" read extra input from the input stream. - In the case of "ping" it is simply a signal to cease the current operation. - "vppctl", in non-interactive mode, will issue a "quit" immediately after the requested command to queue up closing of the session. - This resulted in "ping" thinking a keypress was seen and returning control to the CLI; the "quit" command however is consumed by the keypress event handler and thus the session does not close. - This patch reworks vppctl slightly to only issue "quit" after the command has completed. In particular it uses the fact that VPP issues NUL bytes as a surrogate prompt between output of commands to signal acknowledgement that the command has completed; vppctl now flags that the quit should be issued after the next such acknowledgement. - Since input it still accepted, the user can still terminate the "ping" early, if desired.
