Updated lldpRemManAddrTable to use all the management ip address associated with interface. (sonic-net#201)
Fixes:- sonic-net#7036 sonic-net#6636 Updated to use prefix of 16 byte instead of 6 byte for Ipv6 Management Address. Confirmed with other Vendor Nos Fixed lookup() so that get-next work correctly from test-cases. Updated all files to use new utility API ip2byte_tuple()
