[SPARK-15271] [MESOS] Allow force pulling executor docker images

tests, manual tests)

remove this)
Mesos agents by default will not pull docker images which are cached
locally already. In order to run Spark executors from mutable tags like
`:latest` this commit introduces a Spark setting
(`spark.mesos.executor.docker.forcePullImage`). Setting this flag to
true will tell the Mesos agent to force pull the docker image (default is
`false` which is consistent with the previous
implementation and Mesos' default
behaviour).
