Support compute-intensive machines

[a-thaler]

Description

As part of #18195 users are asking for support of compute intensive types.
As this are specialised machine types for special usage scenarios, these machines should be available under additional worker pools only (#18709).

We will get started with one machine family per hyperscaler to get the new type category introduced and the later on extend with more families.

Current proposal is to get started with these types:
AWS: C7i
GCP: c2d-high-cpu
Azure: fsv2

Criterias

• Users can select the new machine family for additional worker pools in the BTP Cockpit service instance parameters
• Users will find the new families documented in the help portal and the pricing is available in the price calculator
• New types are getting charged (for now by adding them to the overall CU), additional metrics will follow as part of the bigger epic
• Kyma modules will not fail when having the new machines available (should not get scheduled on them except of DaemonSets)

Tasks

• Agree on the concrete types and CU calculation (verify if they are available in all regions)
• Enable metering for the types
• Assure that modules with DaemonSets are tested on the new machine types
  • telemetry
  • rma
  • istio (Support for compute-intensive machine types istio#1260)
• Add support to KEB and document the new types
• Enhance quota monitoring and adjustment to support new machine requests
• Adjust price calculator
