[schematic-230] propagate user ids as attribute to spans

[linglp]

Problem

When looking into a trace on Signoz, currently we have trace down user id in init span. This PR is to make sure that user id can be propagated to the top level span and also most of other span.

example screen shots that demonstrate the problem:

Here you could see "user id" contained a random string

And spans such as "query file view" do not contain a user id

Note: if a span has already ended we cannot add user id back to it. As an example, ManifestGenerator::create_manifests has two children, one is DataModelParser::parse_model, and another one is ManifestGenerator::create_single_manifest. We could propagate user id back to ManifestGenerator::create_manifests, but not DataModelParser::parse_model since this step happened before and ended by the time that the user id is available.

Solution

Borrowed attribute propagation function here to propagate attributes from parent to child, and when the span ends, propagate attribute from back to parent.

Now the user id attribute can be shown in most of the spans.
