packaging: Updated otopi for fully automated execution

This patch updates an otopi engine-setup plugin to allow
a completely automated setup execution with the additional
config file provided on command line. This allows a flow
similar to one using an "answerfile" in the legacy setup.

Additionally, this patch updates parameters for the automated
cleanup flows, so they also can be done in unattended mode.

This patch updates the handling of the following constants:

OVESETUP_APACHE/configureRootRedirection
OVESETUP_APACHE/configureSsl
OVESETUP_CONFIG/isoDomainMountPoint
OVESETUP_DIALOG/confirmSettings
OVESETUP_CORE/engineStop
OVESETUP_CORE/remove
