Fix hostonly network couldn't be found

Name parameter was not included in hostonly config options.
So host only network couldn't be found by Network ID.
This fixes it.
driver: Added 'bound_to' parameter to the 'read_host_only_interfaces' result
network: Added support of 'name' parameter for 'private_network'

If 'name' is specified, then it will be used for search the existing network interface, instead of matching the network addresses.
If this interface does not exist, then it will be created.
action/prepare_nfs_settings: Supported both of 'name' and 'bound_to' parameters

While searching the enabled host_only interface, its name should be matched with 'name' (if PD version >=10)
or with 'bound_to' (if PD version< 10)
