Tests: LayerTest.test_dynamic_http_port is flaky #772
Description
Problem
Because some spots of the test suite are flaky, after recent refactorings, we are now receiving this
tests/testing/test_layer.py:315:
crate_layer = <crate.testing.layer.CrateLayer object at 0x103b1fac0>
def num_cluster_nodes(crate_layer):
> sql_uri = crate_layer.crate_servers[0] + "/_sql"
^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Details
Apparently, the problem is mostly happening on macOS?

We didn't observe this on CI recently.
