Add commands for generating Restricted API Access configuration

[jzelinskie]

It's a bit clunky writing configuration for Restricted API Access outside of the authzed dashboard. Zed could support commands that help maintain best practices

very basic strawman:

zed api-config init
zed api-config token create my_microservice
zed api-config role create admin ReadSchema
zed api-config policy create microservice_with_admin my_microservice service_account admin
