[hidi] `hidi transform` can't be cancelled or aborted. Process needs to be killed manually.

[MaximRouiller]

Steps to replicate

From the PowerShell command line, running the following command:

hidi transform -cs "https://graph.microsoft.com/v1.0/`$metadata" -f Yaml -o .\microsoft-graph.yaml -co

Microsoft.OpenAPI.Hidi.exe starts and consumes 25% CPU and memory usage starts increasing over 2GB. Tried to CTRL-C from the command line which would normally terminate the process. Memory usage continued climbing to ~6GB without completing.

Expected behavior

CTRL-C should abort the transformation process immediately or within a few seconds. Manually killing the Microsoft.OpenAPI.Hidi process should not be required.

You will struggle to process the complete public metadata on Graph because there are a number of containment annotations that are lies for legacy reasons. Unfortunately the lies cause the size of the OpenAPI description to become massive. We have an XSLT that "fixes" the lies before processing for SDK generation. This is one reason that we publish our pre-generated OpenAPI description in the https://github.com/microsoftgraph/msgraph-metadata repo.

Thanks for the workaround! Let's make sure that we still can "cancel" or "abort" any CLI commands we do. 😄
