[fix][query] Filter out tracing for access to static UI assets

[mahadzaryab1]

Which problem is this PR solving?

• Fixes Access to UI static assets should not be traced #6265

Description of the changes

• Adds a filter from xconfighttp to ignore accesses to static UI assets at /static/*

Testing

I ran the monitor example and accessed the Jaeger UI to test that the traces were getting recorded on main but not in this PR.

On main

curl -s "http://localhost:16686/api/traces?service=jaeger" | jq -r '.data[].spans[] | select(.operationName | startswith("/static")) | .operationName'
/static/jaeger-logo-CNZsoUdk.svg
/static/index-bzTJ6oK_.css
/static/index-BDRwFQ_z.js

This PR

curl -s "http://localhost:16686/api/traces?service=jaeger" | jq -r '.data[].spans[] | select(.operationName | startswith("/static")) | .operationName'

1. ^/static/.* does not require regex, can be matched with strings.HasPrefix
2. it doesn't look like it will work if the UI is running with a custom base path, we need to account for that too

[mahadzaryab1]

@yurishkuro for 2 - do we want to do a contains to see if the /static path is anywhere in the URL?

[yurishkuro]

that would be a bit fuzzy. I would rather use HasPrefix with basePath + "/static/"

[mahadzaryab1]

done

[yurishkuro]

git diff cmd/jaeger/config.yaml

   jaeger_query:
+    base_path: /foobar
     storage:
       traces: some_store
       traces_archive: another_store

$ go run ./cmd/jaeger --config ./cmd/jaeger/config.yaml

Reload UI a few times, observe span /foobar/static/favicon-BxcVf0am.ico

So, not solved.
