* \brief Set up testing environment and run the given tests on a cluster.
*
* There are multiple actors in this file with similar names (runTest, runTests) and slightly different signatures.
*
* This actor is usually the first entry point into the test environment. It itself doesn't implement too much
* functionality. Its main purpose is to generate the test specification from passed arguments and then call into the
* correct actor which will orchestrate the actual test.
*
* \param connRecord A cluster connection record. Not all tests require a functional cluster but all tests require
* a cluster record.
* \param whatToRun TEST_TYPE_FROM_FILE to read the test description from a passed toml file or
* TEST_TYPE_CONSISTENCY_CHECK to generate a test spec for consistency checking
* \param at TEST_HERE: this process will act as a test client and execute the given workload. TEST_ON_SERVERS: Run a
* test client on every worker in the cluster. TEST_ON_TESTERS: Run a test client on all servers with class Test
* \param minTestersExpected In at is not TEST_HERE, this will instruct the orchestrator until it can find at least
* minTestersExpected test-clients. This is usually passed through from a command line argument. In simulation, the
* simulator will pass the number of testers that it started.
* \param fileName The path to the toml-file containing the test description. Is ignored if whatToRun !=
* TEST_TYPE_FROM_FILE
* \param startingConfiguration Can be used to configure a cluster before running the test. If this is an empty string,
* it will be ignored, otherwise it will be passed to changeConfiguration.
* \param locality The client locality to be used. This is only used if at == TEST_HERE
