sairedis: add RedisPipeline instance(redispipeline enabled by default…

…) to construct producer g_asicState (sonic-net#336)

* create RedisPipeline obj by default constructor , which enabled redispipeline with parameter 128
* create producer g_asicState using redisPipeline instance with redispipeline enabled
* with the changes in swss and swss-common, route performance improved by 200~300 routes/sec
