Adding completion extension loading and execution logic (#833)

* Adding ICompletionExtension interface

* Adding extension loading and execution logic

* Fixing compilation error in VS 2017

* Using MEF for completion extension discovery

* using await on GetCompletionItems

* Adding an integration test for completion extension and update the completion extension interface

* Update the completion extension test

* Fix issues based on review comments

* Remove try/cache based on review comments, fix a integration test.

* More changes based on review comments

* Fixing SendResult logic for completion extension loading

* Only load completion extension from the assembly passed in, add more comments in the test

* Adding right assert messages in the test.

* More fixes based on review comments

* Dropping ICompletionExtensionProvider, load assembly only if it's loaded at the first time or updated since last load.

* Fix based on the latest review comments

* Adding missing TSQL functions in default completion list

* Update jsonrpc documentation for completion/extLoad
