ACL Consul Tokens

[vankosa]

The possibility of using tokens is required when the consul uses ACL mechanisms, otherwise service discovery does not work by means of consul

In general, an option is needed (for example, consul_token in [servers.default .discovery]), which will be processed by api in the form http://localhost:8500/v1/agent/services?token=123, where 123 is the required token, which has access to the described services
