v0.8.0

Release notes

Added

• compile_commands.json is now also copied to the top west directory. This
  enables clangd to work as intended in ncs and zephyr folders (#53).
• Section in docs/configuration.md document describing release build type.

Changed

• Samples (which inherently do not have a build type) have their build type
  marked with forward slash "/" instead of "None" in the Job table that
  appears when running east release (#52).

Fixed

• Sample binaries had incorrect -None build type qualifier in their release
  name, when they shouldn't have. Incorrect build type qualifier was removed
  (#52).
• Samples can now inherit from release build types (#47).
• east release command now correctly copies build artefacts when
  merged.hex is not generated. Additionally, new Copied build artefacts
  section in docs/configuration.md now exactly defines which build artefacts
  are copied and renamed in release procedure (#51).
