This PR defines a new function supportGuestMemoryHotplug that
clearly defines if the architecture supports memory hotplug. The function
can be reimplemented in virtcontainers/qemu_$arch.go file for each
architecture.

In order to support use cases such as containerd-shim-v2 where
we would have a long running process holding the sandbox pointer,
there would be no reason to call into the stateless functions
PauseContainer() and ResumeContainer(), which would recreate a
new sandbox pointer and the corresponding ones for containers.

Bind back the nic's MAC in HotDetach. So we don't need to modify
nic's MAC in description to hotplug it again.

Got "docker: Error response from daemon: OCI runtime create failed:
QMP command failed: unknown." when "docker run --privileged" with kata.
In qemu part, it got:
"Could not open '/dev/sr0': Read-only file system"
or
"No medium found"
The cause is qemu need open block device to get its status.
But /dev/sr0 is a CDROM that cannot be opened.
This patch let newContainer doesn't attach device if it is a CDROM
to handle the issue.

Now that Interface structure includes the useful information about
the type of interface, Kata does not need to do any assumption about
the type of interface that needs to be added.

This commit replaces every place where the "types" package from the
Kata agent was used, with the new "types" package from virtcontainers.
In order to do so, it introduces a few translation functions between
the agent and virtcontainers types, since this is needed by the kata
agent implementation.

Instead of relying on the kata agent to define generic structures,
the logic is to define those as virtcontainers "types" package.
This way, all consumers of those structures, such as kata-runtime,
kata-netmon, and kata-containerd-shim, don't have to import some
dependency from the kata-agent.

Add host cgroup support for kata.
This commits only adds cpu.cfs_period and cpu.cfs_quota support.
It will create 3-level hierarchy, take "cpu" cgroup as an example:
```
/sys/fs/cgroup
|---cpu
|---kata
|---<sandbox-id>
|--vcpu
|---<sandbox-id>
```
* `vc` cgroup is common parent for all kata-container sandbox, it won't be removed
after sandbox removed. This cgroup has no limitation.
* `<sandbox-id>` cgroup is the layer for each sandbox, it contains all other qemu
threads except for vcpu threads. In future, we can consider putting all shim
processes and proxy process here. This cgroup has no limitation yet.
* `vcpu` cgroup contains vcpu threads from qemu. Currently cpu quota and period
constraint applies to this cgroup.

Some agent types definition that were generic enough to be reused
everywhere, have been split from the initial grpc package.
This prevents from importing the entire protobuf package through
the grpc one, and prevents binaries such as kata-netmon to stay
in sync with the types definitions.

Move to golang version 1.10.4 -- the oldest stable golang release at the
time of writing -- since golang 1.10+ is needed to make namespace
handling safe.
Re-ordered a couple of structs (moved `sync.WaitGroup` fields) to keep
the `maligned` linter happy. Previously:
``
virtcontainers/pkg/mock/cc_proxy_mock.go:24:18⚠️ struct of size 160 could be 152 (maligned)
virtcontainers/monitor.go:15:14⚠️ struct of size 80 could be 72 (maligned)
```
See:
- https://github.com/golang/go/issues/20676
- 2595fe7fb6
Also bumped `languages.golang.meta.newest-version` to golang version
1.11, which is the newest stable release at the time of writing.
Fixes#148.

Instead of using ethtool for getting the driver for network
devices, use sysfs instead. This is because in case of virtio
devices, ethtool returns virtio-net instead of virtio-pci for
virtio network devices. We need to bind/unbind from virtio-pci
driver in case of virtio-net devices.
