Too many "trace" packages

[bogdandrutu]

import "go.opentelemetry.io/otel/api/trace"
import "go.opentelemetry.io/otel/sdk/trace"
import "go.opentelemetry.io/otel/sdk/export/trace"

It is very hard to work with all of these. Would suggest maybe use different names, maybe consider:
sdktrace for "go.opentelemetry.io/otel/sdk/sdktrace"
exptrace for "go.opentelemetry.io/otel/sdk/export/exptrace"

We discussed this in the SIG, and think that probably users should rename these imports as needed. Only SDK maintainers and exporter maintainers will have this trouble. Also note, e.g., in the metrics code we remap go.opentelemetry.io/otel/sdk/export/metric as

import export "go.opentelemetry.io/otel/sdk/export/metric"

That is not true, I have this problem in my main file because I need to configure SDK/API and exporter.

[bogdandrutu]

Also in tests because I need to use the test exporter

This is partially related to #964. I think we can try to do the same in the SDK and SDK exporter package.

Closing as there is not a desire to resolve across the SDK or API packages. The export package will likely be addressed in #1380
