Rollup metadata is not available in options hook

[AgronKabashi]

According to the documentation and #2394, this.meta should be available in all plugin hooks. This does not seem to be the case for options however.

• Rollup Version: >=0.65, 1.0
• Operating System (or Browser): MacOS Mohave 10.14.2
• Node Version: 9.3 & 10.3

How Do We Reproduce?

// Save this as test.config.js
export default {
  input: "test.config.js",
  output: {
    file: "build.js",
    format: "cjs"
  },
  plugins: [
    {
      resolveId () {
        console.log("ResolveId:", this.meta);
      },

      buildStart () {
        console.log("BuildStart:", this.meta);
      },

      options () {
        console.log("Options:", this.meta);
      }
    }
  ]
};

Run with npx rollup -c test.config.js

Output:

Options: undefined
BuildStart: { rollupVersion: '1.0.0' }
ResolveId: { rollupVersion: '1.0.0' }

Expected Behavior

The option hook should have access to the this.meta object and output the proper rollup version.

Actual Behavior

The option hook doesn't seem to have the proper context and thus this.meta is unavailable.
