add process.lazyEnv 

Monitors the status of typings acqusition from TS. If we are acquiring typings, in the completion item provider, return an error result that informs the user that the results are incomplete. Typings acqusition is currently capped at 30 seconds per typings install event so that we don't block intellisense forever if something goes wrong

**Bug**
In the calls to `JSON.stringify`, we are currently passing in `[]` as a whitelist. This results in no argument values being printed.

**Fix**
Pass in null instead so that we print all argument values
