Repairnator proposes multiple patches

[martinezmatias]

How should Repairnator behave when it finds two or more patches that fix a bug and it cannot determine which of them is better? (e.g., the ranking of those patches are close)

Instead of creating a PR with one of those patches, Repairnator could a) create an Issue instead of a PR b) commit each candidate patch into a different branch c) in the issue, Repairnator asks which patch the developer considers the better (e.g., Repairnator adds the links to the mentioned commits so the developers can see the patches inside the issue) d) according to the developers' response (It would require to parse and analyze the issues' comment), Repairnator proposes a PR, using the existing mechanism.
