Migrate to the new conversion generator - part1

This PR contains two commits:
- few more fixes to the generator
- migration of the pkg/api/v1 to use the new generator

The second commit is big, but I reviewed the changes and they contain:
- conversions between types that we didn't even generating conversion between
- changes in how we handle maps/pointers/slices - previously we were explicitly referencing fields, now we are using "shadowing in, out" to make the code more generic
- lack of auto-generated method for ReplicationControllerSpec (because these types are different (*int vs int for Replicas) and a preexisting conversion already exists

Most of issues in the first commit (e.g. adding references to "in" and "out" for slices/maps/points) were discovered by our tests. So I'm pretty confident that this change is correct now.
