Consider the `required` attribute in the Compose schema when providing code completion

[rcjsuen]

services:
  test:
    develop:
      

Given this file, when using code completion we get watch as an array. Since "required": ["path", "action"] is set for the array's items we should ideally also automatically provide path and action when using the completion item for watch.
