Description

Problem: the first request of a new client is somehow 10x slower on v5 (100ms vs 10ms)

Research direction

Reproduce the supplied Benchmark.realtime comparison for build_kubeclient(...).get_entity(...) on v4, v5, and master, then trace the first-request path to locate the source of the latency difference. Done means the v5 first request no longer shows the reported ~10x slowdown; the issue names no files or tests.
