You can file an issue on GitHub, yes:
https://github.com/ClusterLabs/resource-agents/issues

Developer resources are finite and we get requests for new agents
regularly. If you're a subscriber to a RHEL or SUSE or something like
that, then I'd recommend filing an RFE through your distribution.
(That would be necessary anyway if you want such an agent to get into
a downstream package.)

You could also write the agent and submit a pull request to get it
merged into the resource-agents repo.
