system tests : more tests

- exec: add test for #5046, in which conmon swallowed chars
  on a large byte transfer

- pod: add 'pod exists' tests, both positive and negative;
  consolidate tests; add '--label', and check in 'pod inspect'
  add 'pod ps' tests

- networking: add test for #5466, in which detached run
  with --userns=keep-id would not forward a port
