Add RestAPISpecsDocsRepos to branch cleanup and update the delete scripts to output limits and telemetry data

[JimSuplizio]

1. Add MicrosoftDocs/AzureRestPreview to the cleanup scripts. There were about 130k branches that were deleted prior to this change. The number of branches in the repository is now at a manageable level.
2. We have a lot of repositories we're deleting branches from and we're also making gh API calls other than branch cleanup. Output some telemetry.
3. If one of the API commands fails, exit the script, don't continue to try and process. The reason being is that if we hit a rate limit we can't continue processing.

The changes in here, right now, are going to be used for information gathering. There's currently no data of how many API calls are being made when the pipeline runs. Further updates will probably be made depending on the findings.
