distribute services between 2 namespaces in e2e DNS scale services test
**What this PR does / why we need it**:
What: Alters the dns scale test, to distribute the scale load of 10K services between 2 namespaces, so that the test does not fail to create the services.
Why: To allow the dns test to proceed.
Expect to Fix#64774 but wont know until it's actually run in e2e tests, so not marking that issue to auto-close on merge. FWIW, it does pass in local tests using hack/local-up-cluster.sh.
