Consider whether we expose a different concept than CircuitId as part of Server-Side Blazor

[rynowak]

SignalR is current doing some design work to make server-side code less likely to use a connection id for application-level concerns.

The Circuit ID has similar usage and meaning (used to identify a client and handshake with the server). We might want to define a different unique ID to use for circuit identification purposes in CircuitHandlers so that these IDs don't leak outside of their original purpose.

@mkArtakMSFT I don't have bandwith to handle this

@rynowak do you have bandwidth to take this over? Or should we simply push it out of 3.0?
