e2e apps: capture expected state before making changes

Browse Source 
Looking up the expected nodes in the goroutine raced with the test making
changes to the configuration. When doing (unrelated?) changes, the test started
to fail:

Oct 23 15:47:03.092: INFO: Unexpected error:
    <*errors.errorString | 0xc001154c70>: {
        s: "no subset of available IP address found for the endpoint test-rolling-update-with-lb within timeout 2m0s",
    }
