Alternative lock store (git, S3, etc.)

[prein]

Would it be hard to make it an option to use either git or s3 (or other) for storing the lock files?

Git should be doable and only requires lines like this to be changed:

gh-action-mutex/rootfs/scripts/lock.sh

Line 17 in 4b87e07

__repo_url="https://x-access-token:$ARG_REPO_TOKEN@github.com/$ARG_REPOSITORY"

S3 is a completely different mechanism and would require a lot more work.

Though personally I don’t need both use cases and would rely on external contribution and testing :)

Quick thought: Terraform's S3 backend relies on DynamoDB for locking. Perhaps S3 doesn't have the facilities to support atomic locking?
