add github issue labels

Adds the standard github issue labels used by AWS SDKs, and a
workflow to add them to the repository. Having these labels helps
with consistency across repos. The workflow doesn't remove old
labels.

Once the labels are added, another PR will be put up to get rid
of the labels file and workflow.
