Microsoft.Extensions.Hosting.Internal.HostTests.HostLifetimeOnStartedDelaysStart failed on rolling build

[krwq]

I've found only a single instance of that in the last month. My guess by looking at the test is that timeouts need to by slightly increased. It would be useful to add a tiny bit more diagnostic to this test

I'm not adding blocking-clean-ci here only because of the low frequency

@maryamariyan since this is affecting some builds can you please disable the test or at least try increasing the timeouts (to i.e. 30s)?
