add --fixed-ip argument to create port0.1.0

add --fixed-ip argument to create port and add list and dict type for unknow option
now we can use known option feature:
 quantumv2 create_port --fixed-ip subnet_id=<id>,ip_address=<ip>
--fixed-ip subnet_id=<id>, ip_address=<ip2> network_id
or unknown option feature:
one ip:
 quantumv2 create_port network_id --fixed_ips type=dict list=true subnet_id=<id>,ip_address=<ip>
two ips:
quantumv2 create_port network_id --fixed_ips type=dict subnet_id=<id>,ip_address=<ip> subnet_id=<id>,ip_address=<ip2>
to create port
Please download: https://review.openstack.org/#/c/8794/4 and
set core_plugin = quantum.db.db_base_plugin_v2.QuantumDbPluginV2 on quantum server side

Patch 2: support cliff 1.0
Patch 3: support specify auth strategy, for now, any other auth strategy than keystone will disable auth,
format port output
Patch 4: format None as '' when outputing, deal with list of dict, add QUANTUMCLIENT_DEBUG env to enable http req/resp print,
which is helpful for testing nova integration
Patch 5: fix interactive mode, and initialize_app problem
