> Currently zookeeper connect/session timeout values for atlas are set to 
> 200/400 ms respectively which are very low and not practical/recommended 
> values. Due to this atlas startup fails more frequently.
> The jira is set recommended values for zookeeper timeout configuration.
> {noformat}
> atlas.kafka.zookeeper.connection.timeout.ms=30000
> atlas.kafka.zookeeper.session.timeout.ms=60000
