   I confirmed it's working as expected.
   I wl add documentation about this as well.
   
   OW operators can configure tags for invokers like this.
   
   ```
   invoker0 ansible_host=${INVOKER0} tags="['v1', 'gpu']"
   invoker1 ansible_host=${INVOKER1} tags="['v1', 'cpu']"
   invoker2 ansible_host=${INVOKER2} tags="['v2', 'gpu']"
   invoker3 ansible_host=${INVOKER3} tags="['v2', 'cpu']"
   invoker4 ansible_host=${INVOKER4} tags="['v1', 'mem']"
   invoker5 ansible_host=${INVOKER5} tags="['v2', 'mem']"
   invoker6 ansible_host=${INVOKER6} tags="['v2']"
   invoker7 ansible_host=${INVOKER7} tags="['v2']"
   invoker8 ansible_host=${INVOKER8}
   invoker9 ansible_host=${INVOKER9}
   ```
   
   Users can add the following annotations to their actions.
   
   ```
   wsk action update params tests/dat/actions/params.js -i -a invoker-resources '["v2", "gpu"]'
   ```
   
   Activationtivation for this action will be delivered to `invoker2`.
   
   The annotations and the correspondinginvokersinvkoers are as follows.
   
   * `["v1", "gpu"]` -> `invoker0`
   * `["v2", "gpu"]` -> `invoker2`
   * `["v1", "cpu"]` -> `invoker1`
   * `["v2"]` -> One of `invoker2`, `invoker3`, `invoker5`, `invoker6`, and `invoker7`
   * `["v1"]` -> One of `invoker0`, `invoker1`, `invoker4`
   * `No annotation` -> One of `invoker8` and `invoker9` is chosen first. if they have no resource, choose one of the invokers with tags.
