[biancaburtoiu]

What does this PR change?

This PR adds 3 resource files:

• cost-analyzer/savings-recommendations-allow-lists-aws.yaml
• cost-analyzer/savings-recommendations-allow-lists-gcp.yaml

These files contain the complete lists of supported instance types for the custom allow lists feature in Savings Recommendations - see https://kubecost.atlassian.net/browse/ENG-2653

The lists are in YAML format for users to be able to easily copy paste their desired items into their values.yaml file at:

kubecostProductConfigs:
    savingsRecommendationsAllowLists:
        AWS: 
            - t2.small
            - ...
        GCP:
            - ...
         Azure:
            - ...

The URLs for these files will be shared as reference in the public API docs for this page, under this PR: kubecost/docs#1123

@biancaburtoiu I think it would be best to include the relevant helm keys in these files so that these files could be cloned, modified, and used as a values file.

@srpomeroy I've modified each of the 3 files to include the corresponding keys - just double checking that's what you expected?

I had to fix your permissions (the bot requires direct account addition, not group membership). Please try again.

@biancaburtoiu amazing work!
@srpomeroy I figured that these are similar in function to the other value files in that folder. We discussed on slack.
