initial code repo

This patch creates initial code repo.

For ceph, luminous stable release will be used for base code,
and next changes and optimization for ceph will be added to it.

For opensds, currently any changes can be upstreamed into original
opensds repo (https://github.com/opensds/opensds), and so stor4nfv
will directly clone opensds code to deploy stor4nfv environment.
And the scripts for deployment based on ceph and opensds will be
put into 'ci' directory.

+# from triaging it.  #8979 itself was random crashes on corrupted memory
+# due to a buffer overflow (for tickets larger than 256 bytes), further
+# inspection showed that vmalloced tickets weren't handled correctly as
+# well.
+#
+# What we are doing here is generating three huge keyrings and feeding
+# them to libceph (through 'rbd map' on a scratch image).  Bad kernels
+# will crash reliably either on corrupted memory somewhere or a bad page
+# fault in scatterwalk_pagedone().
