Random "curl: (52) Empty reply from server" error when creating a cache

[galderz]

Example.

The creation of the default cache fails:

{"level":"error","ts":1579005228.9610772,"logger":"controller_infinispan"
,"msg":"failed to create default cache for cache service"
,"Request.Namespace":"namespace-for-testing","Request.Name":"test-cache-service"

And so the test fails when using it:
