Remote restore support for Medusa (#454)
* Add MedusaTask API with support for purge, sync and restore prep, and implement remote restore. The PrepareRestore grpc call will have Medusa compute the mapping between the backup and restore clusters, and store it in the local storage. This will allow the restore init container to know which mapping should be performed, without having Cassandra up. * Upgrade to Medusa 0.13.1
