Bump code base to CNI 1.0.0

[masap]

This PR does not update version of coil itself. Just updates only code base.

1. IPConfig.Version is removed. So use trick to know the IP address version.
2. ip.SetupVethWithName() now can receive container MAC address.
3. type of protocolId is modified from int to netlink.RouteProtocol.
4. Fix golang.org/x/sys to version v0.0.0-20210608053332-aa57babbf139 to avoid failure of make generate.
5. Run go mod tidy -compat=1.17 at coil-migrator/.
6. Set cniVersion to result to fix the coredns pod boot failure. e2e test fails with this message and

Hello ! I am new to this project. I already ran make test. Should I run any other test ?

[ymmt2005]

Thank you! I have allowed this PR to run CI, so please see the results.

[masap]

OK. Thanks !

[masap]

The failure of make generate seems to be caused by this issue https://githubmemory.com/repo/kubernetes-sigs/controller-tools/issues/613. So fix the golang.org/x/sys to version v0.0.0-20210608053332-aa57babbf139.

[ysksuzuki]

Thank you for your contribution! This PR is for #173, isn't it? I will take a look.

[masap]

Is this PR for #173

Yes, but just a part of it.

[ysksuzuki]

One more thing, we need to add 1.0.0 to support CNI v1.0.0 here

[masap]

Yes, It will be fixed also at 1.0.0.

[masap]

I mean next step.

[ysksuzuki]

Please resolve conflicts. We merged a security fix and another high-priority PR first. Sorry for bothering you.

[masap]

Rebased.

[masap]

The situation is little bit complicated. This is the summary.

1. Adding CNI version to Result is needed to avoid the warning of coredns pod. result type supports [1.0.0] but unmarshalled CNIVersion is "".

2. Remaining to 0.4.0 is needed to avoid the another warning of coredns pod. unsupported CNI result version "1.0.0".

[ysksuzuki]

Looks like this PR is ready to be merged. Do you still have any concerns?

[masap]

No, I do not.

[ysksuzuki]

Thank you for your contribution!
