synchronize migrations files from the installed or updated bundle
to the root bundle

The destination migration dir may be configured in root package with
`app-migrations-dir` key. Default to `app/DoctrineMigrations`

The migrations files are searched in __bundle_path__/Resources/migrations
OR in the path defined by the 'migration-source' directory in the extra
package information defined in package's composer.json file.

If the file is already present AND equal the script ask user for a confirmation
to copy them.
