[SPARK-23155][DEPLOY] log.server.url links in SHS
## What changes were proposed in this pull request?
Ensure driver/executor log availability via Spark History Server UI even if
the original NodeManagers are gone. The patch is a minimum viable prototype
that assumes access to NM's yarn conf with a fixed RPC port on a SHS machine
because it does not add anything to the event log regarding YARN nodeId.
## How was this patch tested?
Manually tested with a pseudo-distirbuted YARN cluster.
