Added new datatype "ipaddr" in sandesh

This patch implements a new datatype "ipaddr" in c++ sandesh library.
ipaddr can store either ipv4 or ipv6 ip address. In c++, ipaddr is same
as boost::asio::ip::address.

Listing out preliminary support for inet/IPv6 in CQL driver/contrail-collector/contrail-query-engine committed as part of CQL driver changes - https://bugs.launchpad.net/juniperopenstack/+bug/1522930

CQL driver has added some support for inet type which is the type to be used for both IPv4 and IPv6 in CQL/cassandra - cql_if.cc. Currently it is disabled via INET_SUPPORT #ifdef. It is missing IPv6 decoding and encoding. Currently the CQL tables are also created using int32_t as the data type for IP addresses, it needs to change to type inet. This is again controlled via INET_SUPPORT in vizd_table_desc.cc. When implementing support in contrail-query-engine, this #define needs to be enabled - DbDataValueType variant needs to add in inet_addr support too.
