ROX-29641: Fix k6 tests

[mtodor]

Description

Initial investigation showed that sensors were properly scheduled and working, but after some additional testing, it turned out that this is not true. It appears that the sensors are not running, which is why the workload is not being created.

Further findings

It looks like the specific node becomes unstable, and sensors scheduled on that node never reach the running state. It's not clear what causes node instability. After additional testing, the most stable solution option is to deploy central without scanner V4 and set sensor memory request higher.
