Hostname or IP address where to bind listening sockets. This config overrides the SPARK_LOCAL_IP
environment variable (see below).
<br />It also allows a different address from the local one to be advertised to other
executors or external systems. This is useful, for example, when running containers with bridged networking.
For this to properly work, the different ports used by the driver (RPC, block manager and UI) need to be
forwarded from the container's host.
