recovery_mds_scale.sh does not use the test framework correctly. It should call run_test for example to start the test and return errors appropriately to the framework.

Without these compliance the test results cannot be correctly logged.

In addition recovery-mds-scale writes some log files to /tmp when they should be written to the log files and so recovery-mds-scale writes the client-job log files to /tmp when they should be written to the log files/, this needs to be corrected so that the logs are recorded as part of the test collateral and sent to Maloo for storage.
