mandos-ctl: Refactor; move parsing of intervals into argument parsing

* mandos-ctl (MillisecondsValueArgumentMixIn.value_to_set): Assume
  that an incoming value is datetime.timedelta(), not a string.
  (add_command_line_options): Add "type=string_to_delta" to --timeout,
  --extended-timeout, --interval, --approval-delay, and
  --approval-duration.
  (TestSetTimeoutCmd, TestSetExtendedTimeoutCmd, TestSetIntervalCmd,
  TestSetApprovalDelayCmd, TestSetApprovalDurationCmd): Change
  values_to_set to be datetime.timedelta() values, and change to more
  appropriate values to test.  Also adjust values_to_get accordingly.
