Is this a BUG REPORT or FEATURE REQUEST?:

feature request in a sense that IPv6 sysctl support is missing,
but it can be a bug, because IPv6 support is broken

What happened:

CNIs fail to set IPv6 address(es) on interfaces, because IPv6 is disabled (sysctl: disable_ipv6=1) in the Pod's network namespace.

What you expected to happen:

IPv6 should work as desired.

How to reproduce it:

Simple DanmNet+Pod definition which requests IPv6 on at least one interface.

Anything else we need to know?:

DANM should take care of IPv6 related sysctls before CNIs are invoked.
