Better integration

[Quramy]

Now I rewrite tsserver.js to override ts.createLanguageFunction . Is there a better way to integrate tsserver and angular's language-service ?

[angelozerr]

@Quramy please see https://github.com/angelozerr/tsserver-plugins I have used your idea to override createLanguageService (many thank's for this great idea!)

The advantage of tsserver-plugin are :

• follow the same idea than the future of TypeScript (declared plugins in your tsconfig.json)
• not rewrite tsserver.js, but concat at runtime teh before.js and the tsserver.js

Thanks again for your great idea!

@angelozerr Thanks.
I'm looking forward to the PR microsoft/TypeScript#12231 😄
