ods-enforcer key list output may need to be changed

The output of the 'ods-enforcer key list' command is quite different to that from 'ods-ksmutil key list' in 1.4. We need to review this to see if we can make it more compatible.

1.4 output:

Keys:
Zone: Keytype: State: Date of next transition:
ods KSK ready waiting for ds-seen
ods ZSK retire 2013-01-21 17:17:00

1.4 has a verbose mode:
