### What changes were proposed in this pull request?
- Reuse the `rpcAskTimeout` variable in LifecycleManager
- Make `rpcAskTimeout` and `rpcRetryWait` lazy in `RpcEndpointRef`. Since
many places are using `RpcEndpointRef` for just endpoint name. Examples are all
the callers using `Dispatcher.postMessage`
### Why are the changes needed?
`rpcAskTimeout` and `rpcRetryWait` are causing 4% of total allocations.
