[QUIC] Client mistakenly recycles tokens across different servers #7197
Description
Problem
The Agave QUIC client libraries use the hardcoded string "connect" as the server name indication for all servers.
This leads quinn's TokenStore to reuse address validation tokens across different servers.
This isn't a problem for Agave servers but it is not spec compliant and can lead to issues with servers that use QUIC retry.
Proposed Solution
A couple possible solutions
1. Use different SNIs
Keep the address validation token store enabled (decreases time to first app_data packet or something?)
Use a different server name indication for every server to prevent reuse.
2. Disable the token store
