[SPARK-5736][Web UI]Add executor log url to Executors page on Yarn

[shenh062326]

Currently, there is not executor log url in spark ui (on Yarn), we have to read executor log by login the machine that executor in. I think we should add executor log url to executors pages.

This needs a rebase already. Is it really necessary to push through UI info like this into all the core code?
