Upgrade containerd api. about cri

[crosbymichael]

Ya, we are doing our final API review so we have something consistent and good for the long term where its versioned as well. Sorry for the churn right now but its best to do this now, before a release, then later.

A quick review of 1040 and 1047 they don't look like major changes just some renames.

Yeah, shouldn't be too hard.
But without rename, cri-containerd won't work with new containerd because grpc requires both sides using the same package name. :)

[Random-Liu]

@crosbymichael Yeah, no worry. :)

Just track the api change here, so that when do rebase we have better ideas what need to be changed.

[crosbymichael]

When we cut the 1.0 alpha it would be a good time to rebase on it

[mikebrow]

main changes:

• rename execution->tasks (we'll need to throw out fake execution for a new fake tasks and events)
• the mount package was moved to types
• execution/task events are now implemented by a new events service
• all services now have the /v1 suffix
• containers.Container_Runtime struct replaced runtime string.. (new struct includes runtime options, something to consider as we move forward)

[Random-Liu]

@mikebrow Thanks! We could keep updating here, so as to make our future rebase easier.

[crosbymichael]

We still have 1-2 API level changes to make before cutting the Alpha. I'll let you know when we do.

Work in progress synching up to the containerd/containerd current master commit 4888d40ac7ca94b914c5f37c1f8129eab2df3790
