Support for datadog gem, instead of deprecated ddtrace gem

[tylerjc]

Good afternoon all!

We're attempting to get our AWS Lambdas instrumented for the first time (with a container image using the guide found here).

I had originally added the two gems it calls out in that guide, but when running bundle install there was a note from datadog that the ddtrace gem is out (or on its way out), and the new thing to use is the datadog gem. Except that doesn't appear to be compatible with the datadog-lambda gem from the looks of testing things out after deploying (stacktrace snippet pasted below).

Is this known/expected with plans to add support for switching to datadog? Or am I missing a piece where it already is possible to use that gem instead of ddtrace?

Any help would be great, thanks!

@DataDog Please update

[duncanista]

Hey sorry,

We are working on upgrading this soon.
First we'll support 3.3, then upgrade the gem on another release!

Sorry for the inconvenience, we haven't had enough bandwidth to support this, but we are now actively working on it.

Any open-source contributions are highly encouraged!

Hey team, sorry I haven't responded on this issue, I've been quite busy working on a product release. Will try to allocate someone in this project as soon as possible

[duncanista]

Working actively on this, added #99 to address some issues

[duncanista]

Still working on it, as it's not fully compatible with the new extension for some reason, need to figure out what might be the issue there!
