[NET-6459] Fix issue with wanfed lan ip conflicts. (#19503) Fix issue with wanfed lan ip conflicts. Prior to this commit, the connection pools were unaware which datacenter the connection was associated with. This meant that any time servers with overlapping LAN IP addresses and node shortnames existed, they would be incorrectly co-located in the same pool. Whenever this occurred, the servers would get stuck in an infinite loop of forwarding RPCs to themselves (rather than the intended remote DC) until they eventually run out of memory. Most notably, this issue can occur whenever wan federation through mesh gateways is enabled. This fix adds extra metadata to specify which DC the connection is associated with in the pool.
