Support qm logs

[MrJnrman]

WIP

Added support for collection Query Monitor logs

Changes in this PR

• If the QIT_TEST_RUN_ID var is present, then send it along with the test run started notification
• Added a PrepareQMLog class that prepares the QM logs.
• If there is logs folder in wp-content/plugins then we send a summary of that data with the test run ended notification.

Note: If no QM log exists, then the original prepared debug log is sent, if the QM log does exists then its sent along with the original prepated debug log.
