common: Adding common library for sample vnf

JIRA: SAMPLEVNF-3

This patch adds common libraries required as part of the
sample vnf.

This includes the following libraries

 1. ACL library
 2. SIP
 3. FTP
 4. Connection tracker
 5. L2l3 stack
    - Interface Manager
    - ARP & ICMPv4
    - ND & ICMPv6
and other common libraries needed for ip pipeline framework
