Rename the exporter directory to exporters (#502) The `go.opentelemetry.io/otel/exporter/trace/jaeger` package was mistakenly released with a `v1.0.0` tag instead of `v0.1.0`. This resulted in all subsequent releases not becoming the default latest, meaning that `go get`s pulled in the incompatible `v0.1.0` release of that package when pulling in more recent packages from other otel packages. Renaming the `exporter` directory to `exporters` fixes this issue by consequentially renaming the package. Additionally, this action also renames all exporters. This is understood to be a disruptive action to existing users as they will need to update any dependencies they currently have on our exporters. However, it was decided to take this action regardless. The need to resolve the existing issue explained above is highly important, and given the Alpha state of this project these kinds of breaking changes should be expected (though not without reason).
