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.

+	# copies of an object the default value--a primary copy and three replica 
+	# copies--reset the default values as shown in 'osd pool default size'.
+	# If you want to allow Ceph to write a lesser number of copies in a degraded 
+	# state, set 'osd pool default min size' to a number less than the
+	# 'osd pool default size' value.
+
+	osd pool default size = 4  # Write an object 4 times.
+	osd pool default min size = 1 # Allow writing one copy in a degraded state.
+
+	# Ensure you have a realistic number of placement groups. We recommend
+	# approximately 100 per OSD. E.g., total number of OSDs multiplied by 100 
+	# divided by the number of replicas (i.e., osd pool default size). So for
+	# 10 OSDs and osd pool default size = 4, we'd recommend approximately
+	# (100 * 10) / 4 = 250.

+	osd pool default pg num = 250
