HACK: Workaround weird paramiko socket behaviour

When the far side disappears, such as on reboot, mdt shell can get
stuck 20 minutes. If we enable keepalive messages and add a timeout
to select() we can detect that tx of keepalives aren't progressing
and emulate a timeout after a more reasonable 20 seconds.
