Harald Jensås 8355e76ca4 Calculate undercloud ctlplane DHCP allocation pools
* Make dhcp_start and dhcp_end optional for subnet definitions
  in undercloud.conf.
* Allow non-contiguous allocation pools for ctlplane subnets

Calcualte the allocation pools by removing the local_ip,
gateway, admin_host, public_host and ``inspection_iprange``,
from the subnets full ip range. Allocation_pools for all
remaining ranges will be configured. A new per-subnet option
``dhcp_exclude`` is added, a list of IP addresses or IP
ranges that will be excluded from the allocation pool. For
example:

  dhcp_exclude = 172.20.0.101,172.20.0.210-172.20.0.219
                   ^ ip addr         ^ ip range

If dhcp_start is defined and dhcp_end is not defined (or vice
versa) any addresses prior to (or after) this address is
removed from the allocation pools.

Make dhcp_start and dhcp_end options ListOpts to enable non-
contigous allocation pools. For example, to create allocation
pools: [{'start': '172.20.0.100', 'end': '172.20.0.150'},
        {'start': '172.20.0.200', 'end': '172.20.0.250'}]
the following configuration can be used in undercloud.conf:

  dhcp_start = 172.20.0.100,172.20.0.200
  dhcp_end = 172.20.0.150,172.20.0.250

A new method is added for remote_subnet_opts, same options as
for the local_subnet_opts but without the defaults.

To allow optional dhcp_start and dhcp_end for the local_subnet
which have defaults defined, a condition is used to ignore
dhcp_start and dhcp_end in case they are the default values
and the cidr is NOT the default.
