Ian Cottrell 2e887e3d13 internal/telemetry: removing the concept of exporter lists
Instead we only have a single exporter, and it must delegate behaviour
to any other exporters it wants to include.
This removes a whole collection of suprises caused by init functions adding
new exporters to a list, as well as generally making things faster, at the small
expense of needing to implement a custom exporter if you want to combine the
features of a few other exporters.

This is essentially the opposite of https://go-review.googlesource.com/c/tools/+/212243
which will now be abandoned in favor of this approach.
