[v2] no way to configure cost of link if using token issue/redeem CLI

[lynnemorrison]

Using the token issue/redeem method I don't see any way to specify link cost. I don't see cost in CRDs access_grant or access_token

skupper site create west --enable-link-access -n west skupper site create east -n east

skupper listener create backend 8080 -n west --selector app=backend skupper connector create backend 8080 -n east --selector app=backend

skupper token issue ~/token1.yaml -n west skupper token redeem ~/token1.yaml -n east

skupper link status -n east NAME                                STATUS      COST west-33b93f9e-5787-41e7-a47a-e947ed4e9270 OK    0

I think we need to add cost to the AccessToken CRD and then ensure that is applied to the link received in exchange before it is written to the API.
