logging improvements

## What changes were proposed in this pull request?
Adding additional information to existing logging messages:
  - YarnAllocator: log the executor ID together with the container id when a container for an executor is launched.
  - NettyRpcEnv: log the receiver address when there is a timeout waiting for an answer to a remote call.
  - ExecutorAllocationManager: fix a typo in the logging message for the list of executors to be removed.

## How was this patch tested?
Build spark and submit the word count example to a YARN cluster using cluster mode
