1.30.0

This change comes packed with features and new integrations thanks to all the nice contributions, along with a few fixes.

Upgrades

• ⚠️ Users of the profiler that call profiler.WithAPIKey() or set a DD_API_KEY environment variable will see a change in behaviour which could result in breaking their profiling integration. Profiles will now be uploaded through the agent running on localhost:8126. If you don't have an agent running there, please use profiler.WithAgentAddr() or the appropriate environment variables to configure the location of the agent. This commit has more details on the exact changes.
