Share-able links for perf discovery that retains expanded metrics settings

There's no way to share a page with someone else with expanded metrics shared.

User Acceptance:

• Any user with the access to view performance discovery for a given project can copy/paste the URL that when opened by someone with access will preserve the metric selection, including the "Use Expanded Metrics" checkbox choices.
• If metric choice and checkbox values are not provided in the url, then defaults for ops/sec and unchecked should be used.
• Any user without the access to view performance discovery for a given project will be presented with the standard "Unauthorized/Login" Dialogue.
