Find ALL paths :)

[robins]

This is helpful when some of the paths are not possible, owing to extension related limitations (PostGIS is a good example of such an extension).

We ideally don't want "all" paths... for e.g. v9.3.14 -> v9.4.20 doesn't need all hops from v9.3.14 -> v9.3.15 and v9.3.14 -> v9.3.16 and so on.

The idea here is to try all possible sensible paths, where the engine is at least upgrading to the next major version.

This dependends on Issue #9

Should be done with the recent work in allopt2 branch (now merged with master). Commit 8f81d9e
