etcd-tester: fix, clean up multiple things (#5462)

Browse Source 
* etcd-tester: more logging, fix typo

* etcd-tester: fix prevCompactRev scope

Fix https://github.com/coreos/etcd/issues/5440.

* etcd-tester: move utils to bottom, clean up logs

And remove stresser operation inside defrag

* etcd-tester: separate update revision call

* etcd-tester: fix cleanup when case is -1
