Deprecate the use of Google Cloud Debugger

Since Cloud Debugger is getting deprecated (doc: https://cloud.google.com/debugger/docs), we should remove it altogether and potentially replace it with Snapshot Debugger (https://github.com/GoogleCloudPlatform/snapshot-debugger)

Cloud Debugger is currently embedded in some services (for example, https://github.com/GoogleCloudPlatform/microservices-demo/blob/main/src/recommendationservice/recommendation_server.py#L128)

Additionally, we should look into closing any potentially-no-longer-relevant issues, for example:

• https://github.com/GoogleCloudPlatform/microservices-demo/issues/538
• https://github.com/GoogleCloudPlatform/microservices-demo/issues/645
• https://github.com/GoogleCloudPlatform/microservices-demo/issues/832

Snapshot debugger only supports Node.js debug agent in preview mode still, looks like Python3 support will come eventually? That being said, are there any fixes we can provide for the above issues linked?

Is it something you could help with during one of your next rotations @arbrown or @minherz?

Can we ensure that the cloud debugger replacement also has corresponding aarch64 support?

we can try to look into it! for now docs are showing that Cloud debugger will be deprecated May 31, 2023 (https://cloud.google.com/debugger/docs/deprecations)

Thanks, @xtineskim, for pointing out that the Snapshot Debugger will lose support after Aug 31, 2023:

Snapshot Debugger and associated agents will be supported until Aug 31, 2023, after which they will be archived and frozen.

In that case, I don't think we should use Snapshot Debugger at all. We should still remove all instances (inside Online Boutique) of Cloud Debugger being used.
