- Performance testing has shown excessive CPU time is spent when local_address() is called within a tight loop, this has been tracked down to the fact that ss::file_desc::local_address() invokes a system call, getsockname. - To mitigate this issue, the connection class now caches the value of local address upon instantiation. - Partially fixes: redpanda-data#15898 (cherry picked from commit 1cc1d1b)
