This fixes a bug where GetIndexedIP would fail to produce correct IPv6 addresses if the IPv6 address contains leading zeros.
As a consequence, perfectly valid IPv6 pod CIDRs like
fd:11::/64
could not be used.This bug has been fixed in upstream for a while: kubernetes/utils#145
Ideally, we sync this package with upstream, as there are likely more such bugs that we have not fixed yet. But it seem upstream has moved quite far from our implementation and moved packages around, so it's unclear what changes we have applied on our side only.
