v0.17.0

BREAKING CHANGES:

• generate: templates using printf with either codefile or tffile to render code examples in markdown will need to switch to using those functions directly.
  For example, switch the following template code:
  {{printf "{{codefile \"shell\" %q}}" .ImportFile}}
  to
  {{codefile "shell" .ImportFile}} (#300)

FEATURES:

• migrate: Added new migrate subcommand that migrates existing provider docs using the rendered website source directories (website/docs/ or /docs/) to a terraform-plugin-docs-supported templates directory. (#314)

ENHANCEMENTS:

• generate: Add provider-schema flag to pass in a file path to a provider schema JSON file, allowing the command to skip building the provider and calling Terraform CLI (#299)

BUG FIXES:

• generate: fix no such file or directory error when running generate with no existing rendered website directory. (#296)
• generate: fix incorrect rendering of example and import files for providers with no docs templates or with generic fallback templates. (#300)
