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.

+
+Understanding the release cycle
+-------------------------------
+
+The development release cycle is two to four weeks long.  Each cycle
+freezes the master development branch and applies `integration and
+upgrade tests <https://github.com/ceph/ceph-qa-suite>`_ for the
+duration of one cycle before it is released and the next release's
+code is frozen for testing.  Once released, there is no effort to
+backport fixes; developer focus in on the next development release
+which is usually only a few weeks away.
+
+There are three to four stable releases a year.  Each stable release
+will receive a name (e.g., 'Jewel') and bug fix backports at least
+until the next stable release is out.
+
+Every other stable releases is a LTS (Long Term Stable) and will
+receive updates until two LTS are published. For instance Dumpling is
+retired when Hammer is published, Firefly is retired when Jewel is
+published etc. The rationale is that backports to a LTS (Firefly for
+instance) are expected to happen until the next LTS is published
+(Jewel is the LTS following Hammer), to fix bugs and possibly
+backport important features. After the next LTS is published,
+backports are still expected to fix bugs with a focus on whatever can
+prevent upgrades to the next LTS (in our example, fixes to Dumpling
+were published after Firefly was released and until Hammer was
+published, primarily to ensure Dumpling cluster can smoothly migrate
+to Firefly).
+
+* Long Term Stable : until the next two LTS are published
+* Stable release : until the next stable release is published
+* Development / testing release : no backports
+
+For each stable release:
+
+* `Integration and upgrade tests
+  <https://github.com/ceph/ceph-qa-suite>`_ are run on a regular basis
+  and `their results <http://pulpito.ceph.com/>`_ analyzed by Ceph
+  developers.
+* `Issues <http://tracker.ceph.com/projects/ceph/issues?query_id=27>`_
+  fixed in the development branch (master) are scheduled to be backported.
+* When an issue found in the stable release is `reported
+  <http://tracker.ceph.com/projects/ceph/issues/new>`_, it is
+  triaged by Ceph developers.
+* The `stable releases and backport team <http://tracker.ceph.com/projects/ceph-releases>`_
+  publishes ``point releases`` including fixes that have been backported to the stable release.
+
+In the timeline, the life time of a LTS is calculated to be
+approximately 18 months after the month of the first release. For
+instance, Dumpling is published August 2013 and 18 months starting
+September 2013 is February 2015, therefore by March 2015 Dumpling
+should be retired. The lifetime of a release may vary because it
+depend on how quickly the stable releases are published. For instance
+although Dumpling theoritical retirement was March 2015, it was
+extended to May 2015.
+
+Release numbers conventions
+---------------------------
+
+The first Ceph release back in Jan of 2008 was 0.1.  That made sense at
+the time.  The versioning scheme did not change until April 2015,
+when 0.94.1 (the first Hammer point release) was published.  To avoid reaching
+0.99 (and 0.100 or 1.00?) we have a new strategy.
+
+* x.0.z - development releases (for early testers and the brave at heart)
+* x.1.z - release candidates (for test clusters, brave users)
+* x.2.z - stable/bugfix releases (for users)
+
+``x`` will start at 9 for Infernalis (``I`` is the 9th letter), making
+our first development release of the 9th release cycle 9.0.0.
+Subsequent development releases will be 9.0.1, 9.0.2, etc.
+
+After a couple months we'll have a 9.1.0 (and maybe 9.1.1) release candidate.
+
+A few weeks after that we'll have the Infernalis release 9.2.0, followed
+by stable bug fix updates 9.2.1, 9.2.2, etc., and then begin work on the
+Jewel (10.y.z) release.
