[local-benchmark tool] Generates URL with parameter setting in the page

[Linchenn]

We could add a function for the local-benchmark tool: Provides a button and when users click it, it would encode all paramter setting in the current page-view and construct an URL.

[pyu10055]

the URL of the benchmark page should reflect the settings dynamically, basically when users copy the url and sharing the settings are shared directly.
the param/value pairs on the url should be url encoded.
