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.

+dashboard plugin
+================
+
+Dashboard plugin visualizes the statistics of the cluster using a web server
+hosted by ``ceph-mgr``.
+
+Enabling
+--------
+
+The *dashboard* module is enabled with::
+
+  ceph mgr module enable dashboard
+
+Configuration
+-------------
+
+Like most web applications, dashboard binds to a host name and port.
+By default, the ``ceph-mgr`` daemon hosting the dashboard (i.e., the
+currently active manager) will bind to port 7000 and any available
+IPv4 or IPv6 address on the host.
+
+Since each ``ceph-mgr`` hosts its own instance of dashboard, it may
+also be necessary to configure them separately. The hostname and port
+can be changed via the configuration key facility::
+
+  ceph config-key set mgr/dashboard/$name/server_addr $IP
+  ceph config-key set mgr/dashboard/$name/server_port $PORT
+
+where ``$name`` is the ID of the ceph-mgr who is hosting this
+dashboard web app.
+
+These settings can also be configured cluster-wide and not manager
+specific.  For example,::
+
+  ceph config-key set mgr/dashboard/server_addr $IP
+  ceph config-key set mgr/dashboard/server_port $PORT
+
+If the port is not configured, the web app will bind to port ``7000``.
+If the address it not configured, the web app will bind to ``::``,
+which corresponds to all available IPv4 and IPv6 addresses.
+
+You can configure a prefix for all URLs::
+
+  ceph config-key set mgr/dashboard/url_prefix $PREFIX
+
+so you can access the dashboard at ``http://$IP:$PORT/$PREFIX/``.
+
+
+Load balancer
+-------------
+
+Please note that the dashboard will *only* start on the manager which
+is active at that moment. Query the Ceph cluster status to see which
+manager is active (e.g., ``ceph mgr dump``).  In order to make the
+dashboard available via a consistent URL regardless of which manager
+daemon is currently active, you may want to set up a load balancer
+front-end to direct traffic to whichever manager endpoint is
+available. If you use a reverse http proxy that forwards a subpath to
+the dashboard, you need to configure ``url_prefix`` (see above).
