IPv6 for Basic Networking
This PR is a proposal for adding very basic IPv6 to Basic Networking. The
main goal of this PR is that the API returns a valid IPv6 address over which
the Instance is reachable.
The GUI will show the IPv6 address after deployment of the Instance.
If the table VLAN has a proper IPv6 CIDR configured the
DirectPodBasedNetworkGuru will calculate the IPv6 Address the Instance will
obtain using EUI-64 and SLAAC: https://tools.ietf.org/search/rfc4862
The template has to be configured accordingly:
- No IPv6 Privacy Extensions
- Use SLAAC
- Follow RFC4862
This is also described in:
https://cwiki.apache.org/confluence/display/CLOUDSTACK/IPv6+in+Basic+Networking
The next steps after this will be:
- Security Grouping to prevent IPv6 Address Spoofing
- Security Grouping to filter ICMP, UDP and TCP traffic

utils: IPv6 EUI-64 address calculator
When given a IPv6 subnet and a MAC-Address it will calculate the
EUI-64 IPv6 address used in SLAAC.

Calculate IPv6 address for Instance in DirectPodBasedNetworkGuru
EUI-64 is used here which calculates the address based on the CIDR and MAC
address. Duplicate addresses are not possible to due to the usage of EUI-64
which makes the code much more simple.
In Basic Networking the NIC of the Instance will have it's IPv6 details
configured in the NIC.
This way the API returns the information which can then be used by other
applications to directly talk IPv6 with the Instance.

ipv6: Update NetworkTO to transfer IPv6 Address and CIDR to Hypervisors
This way the StartCommand for KVM contains all the required information
needed to program Security Groups in such a way that IPv6 Address spoofing
is not possible.
