The min and max queue resizing tests sometimes fail due to timing issues. Since the queue resizing is already removed for 8.0 (elastic#52280), there is less incentive to debug the flakiness. Given there are some other tests of queue resizing, and the feature is already removed in upcoming versions of ES, this commit removes the flaky tests. closes elastic#71476

The
fixed_auto_queue_sizethread pool holds a fixed size of threads to handle the requests with a bounded queue for pending requests that have no threads to service them. It's similar to thefixedthreadpool, however, thequeue_sizeautomatically adjusts according to calculations based onLittle's Law. This dynamic adjustment was, by default, disabled for the two
fixed_auto_queue_sizethread pools (searchandsearch_throttled).As this feature was marked as experimental, and we are unaware of any users explicitly configuring this, we intent to deprecate it in ES 7 and remove it in ES 8.
