Issue MESOS-4196: Enable running tests without authorizer.
We do not support creating {{Master}} instance without an {{Authorizer}} in tests: https://github.com/apache/mesos/blob/aa497e81c945677c570484a8aa1a8c8b2e979dfd/src/tests/cluster.cpp#L217. This leads to a segfault when {{masterFlags.acls = None();}} is used in a test, while it's a valid use case and should be allowed. Alternatively, we use {{masterFlags.acls = ACLs();}}, which triggers creation of {{LocalAuthorizer}} with emtpy {{ACLs}}, which seems to be semantically equal to the absence of an authorizer, given {{permissive}} flag is {{true}}. This equivalence should be verified by a test.
