refactor(FDS): Terminate the FDS supporting (#1695)

#1644

As it known, the [FDS](https://docs.api.xiaomi.com/fds/introduction.html)
is a Xiaomi internal storage system, the community users are not possible
to use FDS as a [Backup](https://pegasus.apache.org/zh/administration/cold-backup)
target, and since Pegasus [2.2.0](https://github.com/apache/incubator-pegasus/releases/tag/v2.2.0)
(released in Jun, 2021), the Backup start to support using Apache HDFS as
the target storage.

This patch terminates the supporting of FDS in the next version. Of course,
we will still fix critical bugs if there are in released versions.

TODO: backup/restore modules have to update.
