    ipatests: allocate pseudo-terminal only for specific command
    
    While "ktutil" does require a pseudo-terminal on particular systems to
    operate, majority of programs do not need it.
    At the same time invoking `ssh` with forced pseudo-terminal allocation
    interferes with sessions multiplexing feature and increases connection
    time. The increase can be as large as 10 seconds in certain cases which
    leads to unexpected EOFs of pexpect utility.
