This is just a cleanup work to hide some of the private state of ReplSetTest so it is easier to encapsulate and add new logic. Also enables strict mode.

|
* unclean shutdowns are not safe. If running without a journal, WT starts up from last
|
|
* valid checkpoint, so should recover.
|
|
*
|
|
* Start a set.
|

* Insert data into collection foo
|
|
* fsync secondary member 1
|
|
* Kill -9 secondary member 1
|
|
* Add some more data in a new collection.
|
|
* Restart member 1.

* Check that it syncs from the last checkpoint and data is there.
