Subject: [PATCH 36/40] check_rhui: read RHUI configuration
Extend the check_rhui actor to read user-provided RHUI configuration.
If the provided configuration values say that the user wants to
overrwrite leapp's decisions, then the patch checks whether all values
are provided. If so, corresponding RHUIInfo message is produced. The
only implemented safe-guards are those that prevent the user from
accidentaly specifying a non-existing file to be copied into the
scrach container during us preparing to download target userspace
content. If the user provides only some of the configuration values
the upgrade is terminated early with an error, providing quick feedback
about misconfiguration. The patch has been designed to allow development
of upgrades on previously unknown clouds (clouds without an entry in
RHUI_SETUPS).
