Annotations for sequences require unwieldy workarounds

[trieloff]

The intuitive way of adding annotation to a sequence is this:

openwhisk.actions.update({
  annotations: { "web-export": true, "raw-http": false },
  name: "mysequence",
  action: { exec: { kind: "sequence", components: ["/myuser/someaction"] } }
});

but the implementation of the client currently assumes that passing an options.action object means that the developer intends to build the whole request body themselves, which means the required call would be:

openwhisk.actions.update({
  name: "mysequence",
  action: {
    namespace: "myuser",
    name: "mysequence",
    exec: {
      kind: "sequence",
      components: ["/myuser/someaction"]
    },
    annotations: [
      {
        key: "exec",
        value: "sequence"
      },
      {
        key: "web-export",
        value: true
      },
      {
        key: "raw-http",
        value: false
      },
      {
        key: "final",
        value: true
      }
    ]
  }
});

While this might not be strictly a bug, it is clearly inconvenient and hard to get right without some assistance from @jthomas.
