make building handlers from json more generic

Problem: version-handler, a new feature that will be added to this
repository will also parse json files from the same directory ipmi-flash
does. Currently buildjson is a mix of some code that can be reused and
other code that is pretty specific to firmware updates; this makes it
hard to reuse the code.

Solution: factor out the generic parts and place it in bmc and then
leave the specific parts in firmware-handler. Also code changes have
been made to buildjson: wrap functions in a templated class that leaves
feature specific parsing as a pure virtual method.

Tested:
Ran the unit tests, which do test the parsing functionality.
