ExecutionTimeComparator: Change default settings to allow more queries to be validated.
Now requiring a diff of 50% instead of 500% before reporting a query.

ExecutionTimeComparator: Change order of query executions when repeating the same query.
Use one server at a time in order to allow it to stabilize, before using the other server. Hopefully this will lead to more stable results.

Previous behavior:
  server0: exec0
  server1: exec0
  server0: repeat1
  server1: repeat1
  server0: repeat2
  server1: repeat2
  server0: repeatN
  server1: repeatN

New behavior:
  server0: exec0
  server1: exec0
  server0: repeat1
  server0: repeat2
  server0: repeatN
  server1: repeat1
  server1: repeat2
  server1: repeatN

Allow/ignore certain semantic grouping errors that may occur during transformer validation of queries with MySQL systems.
The goal is to easily be able to use sql_mode=ONLY_FULL_GROUP_BY with MySQL when the Transformer validator is used.
Without this change, all errors caused by this sql-mode would cause the test to abort with STATUS_ENVIRONMENT_FAILURE.

This change allows the following MySQL errors to be produced by Transformers, hence allowing the test to continue:

In normal mode each of these errors will be mentioned in the test output the first time they occur, and further errors will be suppressed.
In debug mode each occurrence of all such errors will be mentioned along with the offending queries.

Other types of semantic or syntactic errors, and executors that are not of the type DB_MYSQL, will still return STATUS_ENVIRONMENT_FAILURE.
