Yaniv Michael Kaul bce09e055c locator/topology: defer expensive format() calls in debug log with value_of() 
Severity: medium

Five format("{}", ...) ternary expressions create temporary strings
for a debug log on every topology node update. Use seastar::value_of()
to defer the formatting to log-time, avoiding 5 heap allocations when
debug logging is disabled.
