[SPARK-13267][WEB UI] document the ?param arguments of the REST API; lift the…

Add to the REST API details on the ? args and examples from the test suite.

I've used the existing table, adding all the fields to the second table.

see [in the pr](https://github.com/steveloughran/spark/blob/history/SPARK-13267-doc-params/docs/monitoring.md).

There's a slightly more sophisticated option: make the table 3 columns wide, and for all existing entries, have the initial `td` span 2 columns. The new entries would then have an empty 1st column, param in 2nd and text in 3rd, with any examples after a `br` entry.
