title: Create a new entity, entity alias in Vault and obtain a token for authentication
body: <p>I would like to create a new entity in Vault and generate a new token to give access to an user to the UI using the API. </p>
  
  <p>So, I am generating the entity using /v1/identity/entity/name/:name, then consulting the mount accessor in /v1/sys/auth and creating a new entity alias with /v1/identity/entity-alias</p>
  
  <p>I am not adding any policy, that's something I will do later, first I just want to give access to the UI.</p>
  
  <p>So now I create the token /v1/auth/token/create, but I don't find a way to associate that token to the previously created entity.</p>
  
  <p>The same example with username/password works as expected.</p>
  
  <p>How do I associate the token to the entity?</p>
