test: add contract tests for converse API (#747)

*Issue #, if available:*

*Description of changes:*
Similar to
aws-observability/aws-otel-js-instrumentation#450
Add converse contract test to validate upstream behavior and be notified
of changes in Converse API support.

The converse_stream test is not included, as botocore is unable to parse
a mocked streaming response - it requires a live HTTP connection to
construct an EventStream object which our infra cannot provide. This is
only covered by the NodeJS contract tests.
