aeon: connect by a credentials found in a config

[oleg-jukovec]

Aeon exports an URI and params to connect into the aeon.grpc role as an advertise URI (not listen):

instances:
  aeon-grpc-router-001:
    roles_cfg:
      aeon.grpc:
        listen:
          uri: 'http://localhost:50051/'
          params:
            transport: 'ssl'
            ssl_key_file: './ssl_cert/server.key'
            ssl_cert_file: './ssl_cert/server.crt'
        advertise:
          uri: 'http://localhost:50051/'
          params:
            transport: 'ssl'

The command:

tt aeon connect -c config instance

Should be able to connect to an instance described in the cluster config.
