script: add script to help format QA review summaries

Run the following command for help:
```
   qa-summary.sh --help
```

This is how the script can be used:
```
   qa-summary.sh < test_failure_tickets.txt
```

Before running the script, prep a 'test_failure_tickets.txt' file
(name is subjective) containing links to all the tracker tickets
you want to format in your test failures summary.

For example:
```
$ cat test_failure_tickets.txt
  https://tracker.ceph.com/issues/68586
  https://tracker.ceph.com/issues/69827
  https://tracker.ceph.com/issues/67869
  https://tracker.ceph.com/issues/71344
  https://tracker.ceph.com/issues/70669
  https://tracker.ceph.com/issues/71506
  https://tracker.ceph.com/issues/71182
```
