ERROR message after not sourced request

[Alex Stafeyev]

[root@controller ~]# designate server-list
ERROR:

We should print the reason and guide the user to source keystone before executing command
example for wanted behavior

[root@controller ~]# neutron agent-list
You must provide a username or user ID via --os-username, env[OS_USERNAME] or --os-user-id, env[OS_USER_ID]
