librbd ports to perl

[Yonghua Peng]

Hello,

There are ruby/java/python/go ports for librbd (ceph's rados block device, see
ceph.com), but there isn't perl's.

For example,

python's - https://github.com/ceph/ceph/blob/v0.48.2argonaut/src/pybind/rbd.py

ruby's - https://github.com/ceph/ceph-ruby/blob/master/lib/ceph-ruby/lib/rbd.rb

Can you show me how to ports that into perl language? I just want to create a
module called Ceph::Lib::Rbd.

Thanks.
