For init processes that use a symlinked WAL directory, or use custom scripts that create new tablespaces, these directories should also be renamed after a failed init attempt, as currently the following errors occur if the first init attempt failed, but a second one might succeed:
fixing permissions on existing directory /var/lib/postgresql/data ... ok
initdb: error: directory "/var/lib/postgresql/wal/pg_wal" exists but is not empty

raise PatroniException('Failed to bootstrap cluster')
patroni.exceptions.PatroniException: 'Failed to bootstrap cluster'
In the remove_data_directory function the same happens for removing the data directory, it seems the same kind of thing should also happen when moving a data directory.
To ensure the data directory can still be used, the symlinks will point to the renamed directories.
