de207a5950 lifecyle: Use lif_address_format_cidr() for IF_ADDRESSES 
Previously IF_ADDRESSES would not contain a prefix length if the address
  entry in the configuration did not was in CIDR format but had a netmask
  set seperately. This commit fixes that behaviour and computes a CIDR
  netmask if necessary.

8a58c0ae6d lifecycle: Expose all adresses and gateways via the environment. 
Gather all IP addresses and gateways and expose them as IF_ADDRESSES and
  IF_GATEWAYS environment variables to executors. This eliminates the need
  to run ifquery from execuctors which would have to parse the config file
  again on every run.

9ee3a874d4 Add support for bonding / LAGs. 
* Add a bond executor
  * Add mappings from ifupdown1/2
  * Add a detailed man page
  * Remove legacy compatiblity glue for setups with 'requires' only

  The current implementation has to work around the fact that member interfaces
  will be already up then the bond is created. This is simply done by downing
  them, adding them to the bundle and upping them again. This can possible be
  done in a nicer way after revisiting the ordering of plugin execution (#12).

  Closes #91

8dc2295006 ifupdown: Don't configure errornous interfaces. 
Do not configure interfaces which have a configuration know to be broken.
  Currently this only happens when using "inherit" to an non-existing iface
  or to an iface and not a template, and having allow_any_iface_as_template
  set to 0.

  In those cases broken ifaces will not be configured unless ifup/ifdown is
  invoked with --force.
