test: fix drift suite

[rschalo]

Fixes #N/A

Description
Drift where the nodepool would be altered during each update and then open up the nodepool to all possible EC2 instances. Some of these instances would be too small and use swap memory which causes kubelet to fail.

Example error:

Jul 12 20:24:01 kubelet[1596]: E0712 20:24:01.933476    1596 run.go:74] "command failed" err="failed to run Kubelet: running with swap on is not supported, please disable swap! or set --fail-swap-on flag to false. /proc/swaps contained: [Filename\t\t\t\tType\t\tSize\t\tUsed\t\tPriority /dev/zram0                              partition\t416>
