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.

+# Mirroring Ceph
+Ceph is primarily distributed from download.ceph.com which is based in the US.
+
+However, globally there are multiple mirrors which offer the same content. Often
+faster than downloading from the primary source.
+
+Using the script found in this directory you can easily mirror Ceph to your local
+datacenter and serve packages from there to your servers.
+
+## Guidelines
+If you want to mirror Ceph please follow these guidelines:
+* Please use a mirror close to you
+* Do not sync in a shorter interval than 3 hours
+* Avoid syncing at minute 0 of the hour, use something between 0 and 59.
+
+## Mirror script
+The 'mirror-ceph.sh' script is written in Bash and will use rsync to mirror
+all the contents to a local directory.
+
+Usage is simple:
+
+<pre>
+./mirror-ceph.sh -q -s eu -t /srv/mirrors/ceph
+</pre>
+
+This example will mirror all contents from the source 'eu' which is *eu.ceph.com*.
+
+### Running with CRON
+The script can easily be run with CRON:
+
+<pre>
+13 1,5,9,13,17,21 * * * /home/ceph/mirror-ceph.sh -q -s eu -t /srv/mirrors/ceph
+</pre>
+
+This will sync from *eu.ceph.com* on 01:13, 05:13, 09:13, 13:13, 17:13 and 21:13.
+
+## Becoming a mirror source
+If you have spare hardware and resources available you can opt for becoming a mirror
+source for others.
+
+A few things which are required:
+* 1Gbit connection or more
+* Native IPv4 **and** IPv6
+* HTTP access
+* rsync access
+* 2TB of storage or more
+* Monitoring of the mirror/source
+
+You can then run the *mirror-ceph.sh* script and mirror all the contents.
+
+### Logs
+The project wants to analyze the downloads of Ceph a few times a year. From mirrors
+we expect that they store HTTP access logs for at least 6 months so they can be
+used for analysis.
+
+### DNS
+Using a DNS CNAME record a XX.ceph.com entry can be forwarded to the server and
+added to the mirror script.
+
+You can request such a DNS entry on the ceph mailinglists.
+
+### Apache configuration
+A Apache 2.4 VirtualHost example configuration can be found the Git repository
+with the name *apache2.vhost.conf*
