If DHCP is configured for IPv4 and IPv6, failing to obtain an IPv6 IP
does not roll back the allocation made for IPv4. This patch rolls back
any changes made in case of failure, so that IP allocation is actually
atomic.

If DHCP is enabled on a zone with subnets, but no subnet has a
dhcp-range configured, then starting a VM will fail because no IP can
be allocated. This patch fixes this by only considering subnets that
have a dhcp-range configured and only failing if there is at least one
subnet with a dhcp-range configured.

If previously an IP was allocated in the IPAM, but a new subnet added
for the other IP version, we need to allocate an IP in the new subnet.

Specify the IP version (4|6) for which an IP shall be requested from the IPAM.

if inside add_dhcp_mapping, which is called at VM or LCX start, we do
not find an IP in IPAM, register the MAC.
This is very useful as a fallback if for some reason an IP mapping was
deleted or there is a bug somewhere that does not register an IP.
This acts more like DHCP to allocate an IP on demand.
In order to properly register the IP, the VMID and hostname is required
as a parameter.

Those methods are used by the DHCP plugins to attain the next free
IP address for a given DHCP range, as well as delete all entries with
a certain MAC address.

Add the option to retrieve the running configuration instead of only
the pending configuration via the config methods. Refactor methods
using the running config to utilize the new parameter.
Add helper methods and return additional attributes from the getter
functions that are needed by the dhcp plugins.

We don't want to routes subnets between different zones when same
exit node is used.

like almost all of our repos do nowadays, modern git can detect such
things on rebase so in development stuff should be hopefully not too
much affected by this.
