ci: clang-tidy for oauth2, storagecontrol

[dbolduc]

My opinion on: #14332 (comment)

Also, I notice that oauth2 previously escaped clang-tidy. Throwing it in the storage shard makes some sense.

This is an improvement, even if the samples for google/cloud/batch are not covered.

the samples for google/cloud/batch are not covered.

True. I missed this. I checked locally and the batch samples are compliant.

I am tempted to throw it in the bigquery shard... But I think I will merge this first.
