The multiversion suite's replica set upgrade logic expects sets to have at least three nodes. Add an arbiter so this test can use said upgrade logic reliably.

/**
|
|
* This test confirms the correct implementation of SERVER-23299. Due
|
|
* to a bug fixed as SERVER-23274, replica set secondaries sometimes
|
|
* fail to clear the "temp" flag on collections that have been renamed
|
|
* as a means of marking the collection as permanent. This
|
|
* particularly happens with collections created by the $out
|
|
* aggregation stage, in versions 3.2.0 through 3.2.1.
|
|
*
|
|
* This test creates a collection using $out in 3.2.1, confirms that
|
|
* the collection gets incorrectly deleted on secondary failover, then
|
|
* confirms that if the user upgrades from 3.2.1 to latest before a
|
|
* failover, then a collection produced with $out in 3.2.1 is not
|
|
* deleted.
