Optimize yml extraction in CompatibleConvertFrom-Yaml

[scbedd]

RE: the script-level variable being used as a module variable.

I can't use simple a $YmlPresent = $null outside of the function, as the way the scoping works out we still end up running get-command repeatedly.

I think this is a safe pattern. Welcome feedback.

I don't have much context on this issue or the module installation work that preceeded it...

Would it make sense for us to install modules from an Azure Artifacts feed that upstreams to PowerShell gallery? That might be faster and more consistent... likely at the cost of efficiency in CI given that yq is already on the agents. https://learn.microsoft.com/en-us/azure/devops/artifacts/tutorials/powershell-upstream-source?view=azure-devops

That's definitely a way to avoid the issue with installing a module!

@weshaggard it looks like Ben and Dan think that I should always use the powershell-yaml, but to use a public feed of ours with upstream to psgallery instead of directly installing the module.

My thoughts if we want to do this:

• Add powershell-gallery as upstream source to azure-sdk-tools public feed
• pull the yaml package into the feed from upstream
• Update `CompatibleConvertFrom-Yaml and Module helper to utilize the yaml version always
  • if I have to pull other packages from upstream I will at this point as well

Do you have any protests to above? If yes, good with that feed?

I have not issues with trying out this approach. I suspect we don't even need to add PS gallery as an upstream if we simply include the package we one on the feed. I'd also be OK creating a feed specifically for PS if that is easier.

I do feel that we should use the azure-sdk-tools public feed, so given that you're good with the process, I'll make this happen.

Thanks @weshaggard

I know @benbp is also looking into this so please coordinate

Yeah @scbedd I'm already working on this. But it can be separate from this work regardless, since they are both achieving different things (reliable downloads vs. not downloading too much)

I'm going to wait on #9392, then update this PR to remove the optional usage of yq. My install loop changes work just fine.

@scbedd I should have it in today, a couple more changes pending.
