feat: add nrdot-collector-host distro

[kb-newrelic]

Summary

• Moved agent config to nr-otel-collector and adjusted Dockerfile accordingly
  • Moved common README-like comments from config to (common) README in distributions to avoid having to repeat it in each config
  • Removed comment about keeping in sync with example repo and created NR-363043 to come up with a more stable process when we have multiple distros
• Copied nr-otel-collector distro and made the following changes
  • replace all occurences of nr-otel-collector with nrdot-collector-host
  • Adjusted manifest to only include necessary/agreed-upon components and regenerated THIRD_PARTY_NOTICES.md
  • delete upload-schema-* instead of adjusting them as we won't need them until we migrated to our new publish process

Exclude README from fileset to avoid regex failing.
Note: If other parts of CI fail cause the assumption of only distro folders under distributions is violated and it's too complicated to fix, we can move the contents of the README somewhere else.
