 All test cases are run sequentially. Test cases which use different
 backends can be run in parallel. As a result total elapsed time can be
 reduced by a great factor.

 This ticket tracks initial planning and work done to speed up the test
 suite.

 Plan: We have decided to fork a child process for each backend run test
 cases related to that backend in the child process. We must devise a way
 to report the progress from
 multiple processes running test cases in parallel. Olly suggested about
 using a pipe to communicate the progress to parent process which performs
 the display job.

 `BackendManagerSingleFile`, `BackendManagerMulti` and
 `BackendManagerRemote` share glass database hence these can't be run in
 parallel.
