This is needed after migration from v1 to v2 and is done in
GitV1UpdateStep.java. Therefore we hat to make the 'forAllPaths' method
in PathBasedRepositoryLocationResolver available in the interface of
RepositoryLocationResolver.
- Mark PathBasedRepositoryLocationResolver as singleton so that other
users will get the same instance and will not overwrite the paths
set by migration.
- Set path kept by InlineMigrationStrategy in location resolver to
store the path.
- Add logging
- Add type of repository to migration web page
