ipa: raspberrypi: Return an error code from Algorithm::read()

Browse source 
When encountering errors, the Algorithm::read() function either uses
LOG(Fatal) or throws exceptions from the boost property_tree functions.
To prepare for replacing boost JSON parse with the YamlParser class,
give the Algorithm::read() function the ability to return an error code,
and propagate it all the way to the IPA module init() function.

All algorithm classes return a hardcoded 0 value for now, subsequent
commits will change that.
