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.

Introduce a new mode that uses tc filters to redirect traffic from
the network interface created by the network plugin to a
tap interface that we connect to the VM.
This mode will help support ipvlan as well.

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.

As we try to make sure we don't pull unneeded dependency when using
QEMU or NEMU as the hypervisor, and because SeaBIOS and OVMF firmware
already handle what's done by the default efi-virtio.rom binary, this
commit gets rid of this dependency by providing a default empty one.

When create sandbox, we setup a sandbox of 2048M base memory, and
then hotplug memory that is needed for every new container. And
we change the unit of c.config.Resources.Mem from MiB to Byte in
order to prevent the 4095B < memory < 1MiB from being lost.

Sort endpoints by name to control the order in which

the VM depends on the order in which it is passed.
Long term we should come up with a more robust approach.

The virt machine type provided by the NEMU project needs to be
supported the same way we support pc and q35 machine types.
First, this patch takes care of adding the hotpluggable block device
capability to this machine type, this way when using devicemapper, we
prevent the code from falling back on using 9pfs instead of SCSI.
It also add one or several bridges to this machine type, as the code
is tightly coupled to the fact that a bridge is required for PCI
hotplug.
At last, it changes the name of the PCI host bridge (main bus), to
use "pcie.0". The default set up from pc machine type "pci.0" is not
suitable for this machine type.

If the memory is reduced , its cgroup in the VM was updated properly. But the
runtime assumed that the memory was also removed from the VM.
Then when it is added more memory again, more is added (but not needed).
