Test manual-mode with ZSK rollover
Similar to previous commit. Parametrize each test case and in case of manual-mode, execute additional checks. First a keymgr run should not change the existing key state (with exceptions of timing events such as moving from RUMOURED to OMNIPRESENT, and from UNRETENTIVE to HIDDEN). Appropriate messages must be logged. After enforcing the next step with 'rndc dnssec -step', the key state should be the same as if the step were to be taken automatically.
