Bug Description

In scaled setup with large VMI, zk connection is lost due to missing heart beat.

In autogenerated vnc code(vnc_api_server_gen.py and vnc_cassandra_client_gen.py), while processing response from cassandra, loops can hog cpu and can cause zk heart beat misses if there are large number of entries.

Add yield to allow zk heart beats

Add yield to allow zk heartbeats

In scaled setup with large number of VMIs, api server restarts are seen due to
missing heartbeats. This could happen due to tight loop which processes large
respose from cassandra.

Add yield to auto generated code to allow zk heartbeats
