Switching to new machine types on aaw-dev cluster

[jacek-dudek]

Reach to cloud native team and/or fin ops to discuss switching to more cost effective machines for system, cloudmainsys, and general nodepools on aaw-dev cluster. Follow up to these issues: #1965, #1993.

Proposed machine models for each nodepool are:
cloudmainsys, system: Standard-D2ds_v5
general: Standard_E4ds_v5

Reached out to Lyly to confirm choice of new virtual machine models and whether there is any special pricing arrangement for other VM models.

Sent more info to FinOps on when and how many machines are expected to be running on the affected nodepools. Waiting for feedback.
