[improve][client] add physicalAddress as part of connection pool key

[heesung-sn]

Motivation

Context: https://github.com/apache/pulsar/pull/22085/files#r1497008116

Currently, the connection pool key does not include physicalAddress (currently logicalAddress + keySuffix). This can be a problem when the same logicalAddresses are in the migrated(green) cluster. (the connection pool will return the connection to the old(blue) cluster)

Modifications

Add physicalAddress as part of the connection pool key
