Treat uninstrumented outgoing peers are instrumented resources in dashboard UI

[JamesNK]

Support for showing uninstrumented outgoing peers in traces page. A fair number of changes were required here because resources are scoped to a browser window (was required because browser language and time was used in some places) while telemetry is static.

• Telemetry changes
  • Resolving uninstrumented peers now happens during data load
  • Peers are re-resolved when resources change
  • Telemetry application is created for uninstrumented peers
  • Traces UI displays peer apps in filter dropdown
  • Traces UI displays peer apps in span summary
• Resource data changes
  • Resource change event for peers now only happens when the resource URLs change, rather than on every change. Perf improvement to prevent it triggering on every status change
  • Dashboard resource client is now a singleton. Done so it can be used from telemetry repository (already singleton) but has the benefit of sharing data if you have multiple browser windows open
  • Dashboard properties has a new display VM. This is so that scoped data (e.g. culture, time) is only applied on display. This change allows resource client to be a singleton
