This looks like it might be related to DNS resolution from cache for k8s universes.

[#5561] Attach CDS to client initializer thread
7353529 
Summary:
Async client initializer uses separate thread to perform it's job.
This thread does not have CDS attached, so it crashes in case of call to RPC thread pool.
Such call is possible when master resolution failed and such result already stored in DNS cache.

Test Plan: ybd --gtest_filter ClientTest.BadMasterAddress
