Add possibility to configure more than one interface per host

[cmeissner]

SUMMARY

We manage (create/delete/configure) hosts via ansible module what works fine for us. But now we need a host which provides two nics with two different subnets aligned to.
As we see in the documentation of the ansible host module (link) there are only single parameter subnet, subnet6 and domain which we assume that these configure the nic.

ISSUE TYPE

It would be great if we'll be able to manage all nics of a host. Maybe convert subnet, subnet6 and domain` into list or dict object to manage more than one interface at all.
A dict can be a better choice to address interfaces by name.

[cmeissner]

As described in API v2 documentation for creating a host. there is an interfaces array. This should be addressed by the ansible module to manage multiple interfaces i guess.

I think that's an duplicate of #757, which we are planning to address soon. Would you agree?

[cmeissner]

Agreed! Is there a valid time schedule already or should we implement a workaround for a while?

[evgeni]

There is no schedule, @Fobhep tried it in #792 but had some issues with it.

Best is probably to have a workaround for now :(
