rCOMMdc0769825150: [services] Tunnelbroker - Skipping session checks in a stream when…

Summary

This diff introduces changes to the bidirectional stream gRPC handler to skip session authentication checks by adding the sessions.skip_authentication config flag.
In case of the flag was provided we are skipping getting the session parameters from the database and expecting the device will be provided as metadata instead. Also, we are creating an empty SessionItem instance to provide compatibility with the following code in the handler. We are adding skipping of the changing of "Online" status for the session in case the flag is provided.

Linear task: ENG-2642

Test Plan

Add the skip_authentication flag to the [sessions] section of the config file.
Connect to the bidirectional messages stream by providing the deviceID parameter instead of sessionID.

The expected result is messages are delivered to the certain deviceID without prior session creation and authentication.

otherwise looks good to me

services/tunnelbroker/src/server/mod.rs
138 ↗	(On Diff #20874)	Outside the context of this diff, but `SessionItem` sounds like a "one of many" object to me. `SessionContext` would be more accurate in describing its purpose, which is to hold some metadata about the current session.

138 ↗	(On Diff #20874)	Outside the context of this diff, but `SessionItem` sounds like a "one of many" object to me. `SessionContext` would be more accurate in describing its purpose, which is to hold some metadata about the current session. That name came from the legacy C++ codebase and refactoring it seems doesn't makes sense now as we possibly switch to Rust totally.
138–146 ↗	(On Diff #20874)	Nit: I'd extract this to an initializer function, sth like `SessionItem::new(device_id: String)` Thanks, @bartek! But this part is a single usage (for our testing Tunnelbroker usage as Redis replacement only) and adding the initializer for that single usage seems maybe overengineering to me.
