Copy files to contaier's rootfs if hypervisor doesn't supports filesystem
sharing, otherwise bind mount them in the shared directory.

If the hypervisor does not support filesystem sharing (for example, 9p),
files will be copied over gRPC using the copyFile request function.

Files are copied over gRPC and there is no limit in size of the files that
can be copied. Small files are copied using just one gRPC call while big files
are copied by parts.

Not all hypervisors support filesystem sharing. Add capability flags to track
this. Since most hypervisor implementations in Kata *do* support this, the set
semantices are reversed (ie, set the flag if you do not support the feature).

Vsock conflicts with factory, when both of them are enabled,
kata will try to create a new vm template which is useless,
thus it's better to return an error directly to let users know
that those two config cannot be enabled at the same time.

The multiqueue flag associated with the TUNTAP network device cannot
be used if the number of queues indicates 0. When 0, this means the
multiqueue is not supported, and we cannot use the according flag.

Since kata-agent is using virtio-console to output debugging info
and the console ports are available in the guest as /dev/hvc0 and
/dev/hvc1, we should swap origin console type 'console=ttyAMA0'
with 'console=hvc0,hvc1'.

Each hypervisor is different and supports different options regarding
the network interface it creates. In particular, the multiqueue option
is not supported by Firecracker and should not be assumed by default.

The point of knowing the number of CPUs from the network perspective
is to determine the number of queues that can be allocated to the
network interface of the our virtual machine.
Therefore, it's more logical to name it queues from a network.go
perspective.

In order to prevent from future duplication of calls into the
hypervisor interface, the hypervisor is directly passed as part
of the xConnectVMNetwork() function. Because this does not apply
the disconnection case, this commit splits the former function
into two separate ones.

- Container only is responsable of namespaces and cgroups
inside the VM.
- Sandbox will manage VM resources.
The resouces has to be re-calculated and updated:
- Create new Container: If a new container is created the cpus and memory
may be updated.
- Container update: The update call will change the cgroups of a container.
the sandbox would need to resize the cpus and VM depending the update.
To manage the resources from sandbox the hypervisor interaface adds two methods.
- resizeMemory().
This function will be used by the sandbox to request
increase or decrease the VM memory.
- resizeCPUs()
vcpus are requested to the hypervisor based
on the sum of all the containers in the sandbox.
The CPUs calculations use the container cgroup information all the time.
This should allow do better calculations.
For example.
2 containers in a pod.
container 1 cpus = .5
container 2 cpus = .5
Now:
Sandbox requested vcpus 1
Before:
Sandbox requested vcpus 2
When a update request is done only some atributes have
information. If cpu and quota are nil or 0 we dont update them.
If we would updated them the sandbox calculations would remove already
removed vcpus.
This commit also moves the sandbox resource update call at container.update()
just before the container cgroups information is updated.

Most of the projects, they can be built with "make". After that,
"sudo make install" can install the application.
It is not work for kata-runtime because kata-runtime's make must work
with golang in the environment that default sudo cannot supply it.
But "make install" doesn't need golang.
So add "GOPATH not set" to handle the issue.

The PR adds the support for s390x.
In the case of CCW devices, the vhost-user devices are not supported.
See #659. An error message is thrown if they tried to be used.
Memory hotplug is not supported on s390 yet and an error message is thrown.
The VirtioNetPCI has been changed to VirtioNet. The generalization
allows to set the VirtioNet to the correct CCW device for s390x.

When agent is configured as longLive, the VM's agent created
by factory will not close it's client once it connected, thus
the sandbox's agent cannot re-connect successfully.
Sharing the agent's client between VM's agent and sandbox
can fix this issue.
