Jedi-language-server

Fixed

- From Jedi's perspective, operations at the beginning of a line now assume they are at position 1. This ensures that hover operations work correctly at the beginning of the line.

Changed

- Diagnostics are now cleared on document close.

Added

- Support for serving content over web sockets.

Changed

- Now support all Python 3.6 versions; we don't need to constrain our runtime requirements to anything less than 3.6 because only our development dependencies require Python > 3.6.0.
- Updated pygls to latest version.

Added

- Initialization options to granularly disable names and full names for hover operations based on their Jedi type. This is useful because some text editors will automatically send hover requests when a user pauses their cursor over text and the large amount of information can get annoying for some users. Resolves: <https://github.com/pappasam/jedi-language-server/issues/147>. Jedi types are currently: `module`, `class`, `instance`, `function`, `param`, `path`, `keyword`, `property`, and `statement`.
- Initialization option to disable hover entirely. If `enable` is set to false, the hover language feature will not be registered. May consider adding something similar to most language server features if this proves useful.

Changed

- In Hover, `Path` has been renamed to `Full name`, which is more accurate and is directly tied to the hover disabling options.
- Restrict Python version support to >= 3.6.2. Upgraded development dependencies. Latest black doesn't support Python < 3.6.2, so to keep things simple here we're now not supporting Python versions below that version either.

Fixed

- Docstring now presents same information as before, but organized more-tersely, (arguably) more clearly, and with much better markdown syntax support. For example, the name / signature has been pulled out from the main docstring and wrapped in python triple back ticks while the docstring is conditionally replaced with the description where relevant.
