Replace validation code with annotations
Instead of having code to validate various values, created POJOs to
represent the decoded data so that bean validation annotations could be
used instead.
Didn't see any obvious ways to use annotations in the Optimization code,
but did notice a bug (passed role instead of provisions). Extracted a
common method which fixed the bug as a side-effect.
