[libvirt] [test-API][PATCH] Add network update test case

[hongming zhang]

The patch add network update test case to cover network update api.
modified: cases/basic_network.conf
- The test suite covers add/modify/delete ip-dhcp-host in network. For other test
scenario, they can be test via customing the conf file.
new file: repos/network/update.py
- So far the network update test case only checking when flag is live or current.
new file: repos/network/xmls/ip-dhcp-host.xml
- Create the ip-dhcp-host sample xml file for adding/deleting ip-dhcp-host
new file: repos/network/xmls/modify-ip-dhcp-host.xml
- Create the ip-dhcp-host sample xml file for modifying ip-dhcp-host
Known bug:
- Bug 985782 - Some flag values of method are missing in libvirt-python bindings
