This adds support to list security-groups mappings and missmatches
between the mappings and backend resources as: firewall-sections and
nsx-security-groups.
e.g -
nsxadmin --resource security-groups --operation list
nsxadmin -r nsx-security-groups -o {list, list-missmatches}
nsxadmin -r firewall-sections -o {list, list-missmatches}
