Fixed

- completionItem/resolve now works again (broke with 0.28.0's migration to pygls 0.10.0)

Added

- signatureHelp now also returns documentation, if available.

Same functions as 0.28, but different tag.

Changed

- pygls `0.10.0`. This version explicitly uses `pydantic` and better supports initialization options. This enables use to remove the `cached-property` dependency for Python versions 3.6 and 3.7.
- pydantic is now used for initialization options parsing. Simplified so much that we were able to remove initializationOption-specific tests.
- Explicitly add method for `did_open`, for some weird reason the latest pygls bugs out if you don't explicitly set this function to at least an empty function.

Removed

- Support for Python 3.6.0. We now only support Python 3.6.1+.
- Monkey patch for `null` versus `missing` attributes. `pydantic` / `pygls>=0.10.0` handles this.

Fixed

- Provide correct version information on `TextDocumentEdit`.

Fixed

- Monkey patched pygls to remove null types from response. This is a temporary fix to more-fully support nvim-lsp et al, necessary until pygls releases its next version.
