This is not needed now that no tests relies on the listener to wait for
a connection to be established before continuing.
* Fix spelling error
* Do not use deprecated options in the otel-collector example

* Add unit tests for context heredity
* Add test that exporter stop is linked to context cancel

* Fix go.mod from rebase
* Remove wrong comment about client stop closing gRPC conn
* Fix shutdown test cleanup
Do not check the second call to the client Stop. There is no guarantee
it will not error in normal operation.
* Make lint fixes
* Fix flaky unit test
Use the internals of the client to explicit cancel the context returned
from exportContext. This gets around the bug where the select in Stop
may randomly choose the non-context Done case and avoid returning an
error (also failing to cancel the context).
* Remove deprecation
To configure the client/exporter with environment variables these
options are used. There is no way to fully remove these options without
removing support for configuration with environment variables. Leave
that decision and strategy determination to a separate PR.
* Fix grammatical error in comment

* Fail in RunEndToEndTest if collector stop fails
* Use testing T.Cleanup to check shut downs
* Add goroutine leak detection
* Fix TestExporterShutdown go leak
The shutdown tests checking if a context error is honored did not
completely clean up the resources used by the client after the error was
evaluated. Update the connection client to handle multiple calls to
shutdown and make a second call to these clients that must succeed so
the test does not have abandoned goroutines.
* Fix leak in TestNew_WithTimeout
The mockTraceService did not delay with its lock being held. This
resulted in the mockCollector stopping and being able to acquire the
lock. It was assumed that no export was taking place because of this and
the mockTraceService was abandoned without cleaning up resources it held
and goroutines it had spawned. This reworks the export blocking logic to
block on a channel read. This will make the block more deterministic and
not depend on the scheduler timing. Additionally, this blocking is moved
inside the lock acquire. Meaning code will deadlock if the block is not
released before a shutdown (something the developer will immediately be
aware of when they submit a bad patch), and will ensure all resources
are released before shutdown.
Replace TestNew_WithTimeout with TestExportSpansTimeoutHonored which
directly tests if a span export errors when the timeout is reached. This
is the only unique thing that TestNew_WithTimeout, but it also tests the
non-error path. That non-error path is tested in many other tests.
* Guard otlptracehttp client stopCh when stopping
In normal operations the exporter is guaranteed to only ever call the
client Stop method once. However in testing we need to call this
multiple times when checking it returns an error in particular context.
Add a lightweight sync.Once to the closing of the stopCh to ensure tests
do not panic when cleaning up.
* Release export block after export
Prevent deadlock in TestExportSpansTimeoutHonored.

Remove nil check on return from NewTestSpanProcessor as it can never be
nil, addressing #2396. Also, add nil checks for testSpanProcessor
methods to prevent panics.
* change resource.Default to be evaluated on first call, rather than on import
* guard defaultResource creation with sync.Once, fallback to emtpyResource
* update CHANGELOG

This is a simple loggin interface to be used interally for the sdk.
Included is an exmaple in `namedtracer` run:
```
cd example/namedtracer
go run . >/dev/null
```
