Refactor workspace devfile logic/spec/fixtures:

  • Default all top-level structures in flattened devfile in initial devfile_flattener, instead of initializing them lazily in subsequent steps
  • Rename and refactor some fixture files
  • Refactor read_devfile_* methods to read_devfile_*_yaml
  • converting processed devfile hash's keys from strings to symbols for easier reference, and to give us the ability to use rightward-assignment destructuring and type safety
  • Other related cleanups for RubyMine inspections warnings
