Martin Atkins a345533573 configupgrade: Beginnings of Upgrade function
This function is the main functionality of this package. So far it just
deals with detecting and renaming JSON files that are mislabeled as
native syntax files. Other functionality will follow in later commits.

Martin Atkins 1132898fbc configupgrade: Load source code for a module and detect already upgraded
This package will do all of its work in-memory so that it can avoid making
partial updates and then failing, so we need to be able to load the
sources files from a particular directory into memory.

The upgrade process isn't idempotent, so we also attempt to detect
heuristically whether an upgrade has already been performed (can parse
with the new parser and has a version constraint that prevents versions
earlier than 0.12) so that the CLI tool that will eventually wrap this
will be able to produce a warning and prompt for confirmation in that
case.

Martin Atkins 2f85b47586 configupgrade: new package for upgrading configs for 0.12
Although the new HCL implementation and configuration loader is broadly
compatible with the prior implementation, it has a number of new idiomatic
forms and it also cannot parse some more extreme non-idiomatic usages
that were possible under the old parser.

To help users migrate to the new implementation, this package will rewrite
configuration to comply with the new idiom and fix as many cases as
possible where the legacy parser was too liberal or exposed implementation
details.
