Simple validation of features

Simple validation of features

Validation is added in StepParseManifest instead of:
 - parser - parsing should not check platform details
 - separate step - there is no feature field in manifest_x

Verification requires installing tpk package with some features and testing
via manipulating /etc/config/model-config.xml

There is only check if feature of given type exists in model-config.xml
