Expose Ip-Family for IPV6 (#1089) (#1098)
Browse files Browse the repository at this point in the history 
### Proposed changes
This PR exposes the `ipFamily` argument to enable creating EKS clusters
that support ipv6 networking.
Modified from #888 and rebased
on top of latest changes in master.

An additional cluster with ipv6 is also created to test that cluster
creation works as expected.

### Related issues (optional)
Closes: #698
Closes: #684
