Improvements

[Neylix]

Description

Fixes some bugs and improve little things

• Fixed telemetry error => buckets expected nb of summaries that was never calculated
• Delete unused functions
• Add max concurrency to a task async as all the response in the workflow should be retrieved fast
• Fix a flaky test
• Update function P2P.broadcast_message as this function should be used as "fire and forget" but it was waiting for all message to be sent and to receive the response.

Type of change

• Bug fix (non-breaking change which fixes an issue)
