Log messages do not have stable argument ordering about grafana-plugin-sdk-go

[oshirohugo]

This issue is happening in github.com/hashicorp/go-plugin
As @joeblubaugh indicated, t's indeed an problem related to unmarshalling and marshalling the logs. The host pipes the plugin logs, unmarshal and marshal it to wrap it into the host logger and the issue comes from this process which is not deterministic.

I created an issue on their repo:
hashicorp/go-plugin#266
And I've also submitted a PR for the issue:
hashicorp/go-plugin#267

Once this is accepted we can update the package and fix the issue

I'm re-opening since the issue isn't actually addressed yet (waiting on upstream submission to hashicorp plugin library).
