The new opentelemetry-sdk-extension-autoconfigure module

[jkwatson]

We have been working steadily over the past weeks to move all of the "auto-configuration" functionality out of the SDK itself and into a new "autoconfigure" extensions module.

What is "auto-configuration"? Anything that will enable configuration of the SDK declaratively, rather than via writing code to do it. This includes, at the moment:

• environment variables
• system properties
• auto-detected SPI implementations

What does this mean for you? If you rely on any of the above, you should make sure you are including the new opentelemetry-sdk-extension-autoconfigure module as a dependency of your project, going forward. If you do not, you will most likely lose functionality that you had previously.
