Adds links to stderr/stdout in the executor tab of the webUI for: 1) Standalone 2) Yarn client 3) Yarn cluster This tries to add the log url support in a general way so as to make it easy to add support for all the cluster managers. This is done by using environment variables to pass to the executor the log urls. The SPARK_LOG_URL_ prefix is used and so additional logs besides stderr/stdout can also be added. To propagate this information to the UI we use the onExecutorAdded spark listener event. Although this commit doesn't add log urls when running on a mesos cluster, it should be possible to add using the same mechanism.
