Closing this in favour of #44 which doesn't introduce a dependency on bootstrap script inside Spark code |

Issue
Spark jobs with a shuffle fail when CNI network is used. The shuffle block fetcher fails to connect to the Executor IP address, which is 0.0.0.0.
What changes were proposed in this pull request?
When launching Executors, instead of hardcoding the Executor IP to "0.0.0.0", use the "bootstrap" utility to get the Executor's IP address. This will return the correct IP address within a CNI network.
How was this patch tested?
Manual test. Fails without this patch:
dcos spark run --submit-args="
--conf spark.cores.max=4 --conf spark.executor.cores=1
--conf spark.mesos.containerizer=mesos
--conf spark.mesos.network.name=dcos
