Hammer CLI

Currently fields prints all fields that start with the field in the list. I like the possibilities this opens but would prefer it to be rather opt-in.

Current state:

hammer host info --id 4 --fields network
Network:            
    IPv4 address: 192.168.121.172
    MAC:          52:54:00:c8:6b:01
    Subnet ipv4:  pichi.example.com
    Domain:       pichi.example.com
Network interfaces: 
 1) Id:           4
    Identifier:   eth0
    Type:         interface (primary, provision)
    MAC address:  52:54:00:c8:6b:01
    IPv4 address: 192.168.121.172
    FQDN:         centos7.pichi.example.com

I would expect only "Network" to be printed as it is what I asked for. Possibility to have 'hammer host info --id 4 --fields network*' for what we see today would be nice and useful.
