hostSupplier is initialized in line 81, i.e
HostSupplier hostSupplier = () -> Collections.singletonList(host);

what will happen to hostsupplier when we have more than one host configured in the RedisProperties file?

there is a possibility of locking the workflowId which is already locked on restart.if the conductor is shutdown with the removing the lock on workflowId, then on restart there is a chance to lock the locked workflowId on retrying the workflow. please handle this scenario

Problem:
Netflix#3450
Solution:
Since Dynomite is the default persistence and queuing mechanism in Conductor, there should be an option to use Dynomite for locking as well.
Approach:
Created dyno-lock sub-project.
Default VotingHostsSelector implementation (VotingHostsFromTokenRange) considers all hosts. This will not work when hosts are used for replication as writing the lock in one node gets replicated in other nodes as well. So we need to to override this.
