CLOUDSTACK-9853: Add support for Secondary IPv6 Addresses and Subnets (#2028)

This commit adds support for passing IPv6 Addresses and/or Subnets as
Secondary IPs.

This is groundwork for CLOUDSTACK-9853 where IPv6 Subnets have to be
allowed in the Security Groups of Instances to we can add DHCPv6
Prefix Delegation.

Use ; instead of : for separating addresses, otherwise it would cause
problems with IPv6 Addresses.

> In addition to have a single IPv6 address (/128) Instances in Basic Networking should be able to have a IPv6 subnet, like a /60 for example routed to them.
> The mechanism for this is DHCPv6 Prefix Delegation. A DHCPv6 server can tell the Instance which subnet is routed to it.
> On the physical router a (static) route needs to be configured to do this. So in Basic Networking it will be up to the network admin to make sure the routes are present.
> The Management Server will pick a subnet for a Instance when needed and configure the VR with the proper DHCPv6 arguments so that the right answer is provided to the Instance.
> For example when running containers it is very nice to have a subnet routed to your Instance so you can give each container a unique IPv6 address.
