Environment details

• OS: OSX 10.13
• Node.js version: v11.7.0
• npm version: 6.5.0
• @google-cloud/bigquery version: 2.0.6

Steps to reproduce

Write this code:

dataset.createTable(
      'name'
      {
        view: {
          query: 'any SQL string',
          useLegacySql: false,
        },
      } as TableMetadata,
    )

The Typescript compiler will complain and say that friendlyName is required, and view must be a string. The types in the API documentation say that friendlyName is optional, and view is an object with some properties.

I discovered this when updating from v1.3 of the library to v2. I'd expect my existing, working library calls to pass type checking, since everything still works if I disable type checking and run the code.
