[Feature Request]: Align diagnostic settings implementation for cross referenced and nested resources

[eriqua]

Description

The implementation of diagnostic settings applied to resources related to the main resource (nested or cross referenced) should be aligned and possibly simplified.

• List modules applying diagnostic on related resources and propose a consistent implementation for all
• Parameter names should be aligned (e.g., sometimes we have pipDiagnostic sometimes publicIPDiagnostic)
• Update guidelines in the wiki

Initial list:

• natgateways and virtual network gateways cross reference PIP and specify pip diagnostic settings parameters
• azure firewall and bastion host cross reference PIP and do not specify pip diagnostic settings parameters, they are implemented directly into the cross referenced module
• VM and VMSS apply diagnostic on pip and nics in a different way as they do not cross reference pip and nic modules. They specify diagnostic settings parameters for both pip and nic

  Note: VMSS pip diagnostic implementation is probably not working (to be tested)

The team opts for implementing this change and discuss elements like the specific naming of parameters based on the proposal in the eventual pull request.
