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).

* draft using stop aggregating on prometheus client (counters)
* remove prometheus client aggregations
Measures are being exported as summaries since histograms doesn't
exist on OpenTelemetry yet.
Better error handling must be done.
* make pre commit
* add simple error callback
* remove options from collector
* refactor exporter to smaller methods
* wording
* change to snapshot
* lock collection and checkpointset read
* remove histogram options and unexported fields from the Exporter
* documenting why prometheus uses a stateful batcher
* add todo for histograms
* change summaries objects to summary quantiles
* remove histogram buckets from tests
* wording
* rename 'lockedCheckpoint' to 'syncCheckpointSet'
* default summary quantiles should be defaulted to no buckets.
* add quantiles options
* refactor test.CheckpointSet and add docs
* flip aggregators merge
