Fixes to mysql-test-run and tests

- Added ORDER BY to get consistent results to federated_server
- Sort slow tests first

mysql-test/lib/My/ConfigFactory.pm:
  Remove usage of port as the test suite is not using that anymore and it causes some probelms in buildbot
mysql-test/lib/mtr_cases.pm:
  Sort slow tests first
  If a test is marked as 'big_test' also mark it as 'long_test'
mysql-test/suite/federated/federated_server.result:
  Added ORDER BY to get consistent results
mysql-test/suite/federated/federated_server.test:
  Added ORDER BY to get consistent results
