mandos-ctl: Add more tests, including tests for all commands

* mandos-ctl (Test_string_to_delta.test_handles_basic_rfc3339): Add a
                                                  few more test cases.
  (TestCmd.setUp.MockClient.Set, TestCmd.setUp.MockClient.Get): Don't
  append to self.calls, since nobody should use it to check for Set()
  or Get() calls; instead, the return value of Get() should be
  inspected, and the MockClient.attributes dict should be inspected
  after (implicitly) calling Set().
  (Unique): New; stand-in for unittest.mock.sentinel.
  (TestPropertyCmd): New; abstract class testing PropertyCmd classes.
  (TestBumpTimeoutCmd, TestStartCheckerCmd, TestStopCheckerCmd,
  TestApproveByDefaultCmd, TestDenyByDefaultCmd): New.
  (TestValueArgumentPropertyCmd): New; abstract class for testing
                                  those PropertyCmd classes which also
                                  inherit from ValueArgumentMixIn.
  (TestSetCheckerCmd, TestSetHostCmd, TestSetSecretCmd,
  TestSetTimeoutCmd, TestSetExtendedTimeoutCmd, TestSetIntervalCmd,
  TestSetApprovalDelayCmd, TestSetApprovalDurationCmd): New.
