Python SDK Truncation Logic

[szokeasaurusrex]

Implement parent issue for Python SDK

What is currently being trimmed:

• request bodies (default: "medium", can be exempted from trimming with "always")
  • possibility to adjust max_request_body_size should stay
  • we can make always the default
• databags (affects local vars too, max breadth: 10, max_depth: 5)
  • limit should be removed
• max value length (trims strings, default: 100 000, (before: 1024, but we increased this because we were trimming ai messages))
  • limit should be removed/bumped very high
• breadcrumbs (max 100)
  • limit should stay
• transport queue (max 100)
  • limit should stay
• spans in a transaction (max 1000)
  • limit should stay
• some integrations have additional trimming logic (Redis: 1024 max data size)
  • limit should be removed
