What

Implement language server for predicate.

Why

The language server protocol (LSP), specified by VS Code team, promises uniform API to support multiple languages and code editors that support LSP. Implementing language server will let us implement integration with predicate linter for once and use the functionality (with minimal update) to support other code editors that support LSP besides VS Code.
