Make SFC installable as a python module

New directory structure:

 <root>/sfc
 <root>/sfc/lib/
 <root>/sfc/tests
 <root>/sfc/tests/functest

JIRA: SFC-60

After installing sfc, the imports would be:

import sfc.tests.functest.x
import sfc.lib.x

+### ODL-SFC TEST2 DESCRIPTION ###
+
+This is a simple description of the test case
+
+We create one client and one server using nova. Then, 2 SFs are created using 
+tacker. The SFs are deployed in two different compute nodes. A chain is created
+where both SFs are included.
+
+vxlan_tool is started in both SFs and HTTP traffic is sent from the client to
+the server. If it works, the vxlan_tool is modified to block HTTP traffic.
+It is tried again and it should fail because packets are dropped
