bonding: settings parser for ifcfg plugin + NMSettingBond class

Introduced a new TYPE=bond for ifcfg-rh configuration files.
Alternatively BONDING_MASTER=yes can be specified instead of
setting the type explicitely to maintain backwards compatibility
with existing configuration files.

Bonding device files require a DEVICE= line to be present which
specifies the virtual bonding interface in the kernel. We do not
allow auto-generation of the name in order to keep confusion to
a minimum when reusing existing bonding interfaces.

The BONDING_OPTS= parameter can be used to specify various bonding
related options, such as:
  - mode
  - miimon
  - updelay
  - downdelay
  - arp_interval
  - arp_ip_target

By default, the NMSettingBond class uses a miimon value of 100 which
seems like a sensible default value for 99% of all configurations.
If this is not suitable, an arp_ip_target needs to be specified
manually.

A writer is not yet implemented.

Changes v2:
 - renamed DeviceName property to InterfaceName
 - moved code to validate device name to dev_valid_name() for future use
