> Identified a thread/resource leaks in CDC code path
> 1. SidecarCdcClient object is being created for each token range inside
> sidecar. This object holds a reference to vertx object which is never closed.
> During failures, new SidecarCdcClient objects are created on each retry
> causing resource leaks.
> 2.SidecarCdcClient is not autoclosable, hence SidecarClient object reference
> by SidecarCdcClient is never closed.
> 3. StatePersister class is started but close is never called in sidecar
> We should have a singleton SidecarCdcClient, adding a constructor parameter
> in SidecarCdc to be able to pass singleton SidecarCdcClient created in
> sidecar. Also making the SidecarCdcClient auto closable to be closed from
> sidecar while managing the lifecycle.
