Many times, configuration values are just boolean values. The Configuration object now only returns the literal configuration value. It would be useful to have this object return True instead of "True" to keep code a bit shorter

- Implemented BaseInstrumentor interface to enable auto-instrumentation
- Added integration tests (same tests as other db integrations)

#658)

There are some examples that are duplicated in the getting started guide and in
the examples folder itself. This commit removes the duplicated examples and
updates the getting started guide to include then from real source files that
are passed through the linter and have tests.

Some build time improvements:

- split lint/docker-tests/docs into their own steps. Since lint is usually the thing that fails anyways, it's good to have it run first. We could make the build depend on this step to prevent slowing other builds waiting in the pipeline (since we only have 5 workers)
- move all pip install commands into a single line per test environment. this reduces the overhead of calling the pip command separately multiple times per environment.
- removed pip upgrade command for pypy3 and py38

Adds instrumentation for python sqlite3 library.

We want to get a json of span without indent, but it's not possible with Span#to_json because the method uses hard-coded indent. We currently use a workaround of json.loads(span.to_json()) which is not efficient in the performance.

This adds DatadogFormatfor extracting and injecting trace contexts with Datadog-specific headers.

renaming otcollector to opencensus, as it's using opencensus under the hood. This was originally intended to be replaced by otlp, by a new package can be created for that instead.

Right now, A resource object attached to a Span can be None. That means that there's two similar objects that refer to an empty resource: None, and the _EMPTY_RESOURCE global.

We should just always default to the _EMPTY_RESOURCE object: this avoids None checks in exporters.

Incorrect import documentation in both pymongo and psycopg2.

Adding support for django 1.10+

Fixes #730

Adding a step to test that uploading packages to pypi should work.

This should prevent issues that occurred in the release of 0.7.0 from happening where a classifier was set incorrectly (3 - Beta), causing pypi to return a 400 and fail publishing packages.

More work to improve release process:

- adding RELEASING.md file to describe release process
- updated prepare_release.sh script to allow it to be run manually by maintainers
- removed workflow to automatically publish PR, current recommendation from otel technical committee is not to use bot accounts

Fix propagation of aiohttp client traces, which were not properly injected previously.

This commit introduces a new boostrap command that is shipped as part of
the opentelemetry-auto-instrumentation package. The command detects

Similar to flask, enabling exclusion of spans based on host and path.

This commit ports the OpenTracing testbed[1] to check that the ot-shim is
working as expected using different frameworks.

Gevent doesn't support context vars yet[2], so those tests are not compatible
with opentelemetry and were not ported.
