TUN-9319: Add dynamic loading of features to connections via ConnectionOptionsSnapshot

Make sure to enforce snapshots of features and client information for each connection
so that the feature information can change in the background. This allows for new features
to only be applied to a connection if it completely disconnects and attempts a reconnect.

Updates the feature refresh time to 1 hour from previous cloudflared versions which
refreshed every 6 hours.

Closes TUN-9319
