32ef29bd18 factory: use customised deep compare
reflect.DeepEqual would return false when comparing nil map/slice with
empty map/slice. We would want to return success in such case, since it
is possible for upper layers to send these kind of configs.

Fixes: #844

07c1f18e51 factory: start proxy after create new VM
The PR moves ahead the start of proxy process for vm factory so that
it waits for both vm and proxy to be up at the same time. This saves
about 300ms for new container creation in my local test machine.

a1537a5271 hypervisor: rename DefaultVCPUs and DefaultMemSz
Now that we only use hypervisor config to set them, they
are not overridden by other configs. So drop the default prefix.

d0679a6fd1 tracing: Add tracing support to virtcontainers
Add additional `context.Context` parameters and `struct` fields to allow
trace spans to be created by the `virtcontainers` internal functions,
objects and sub-packages.

Note that not every function is traced; we can add more traces as
desired.

Fixes #566.

bdd5c66fc5 virtcontainers: add vm factory support
Add vm factory support per design in the VM Factory plugin section.
The vm factory controls how a new vm is created:

1. direct: vm is created directly
2. template: vm is created via vm template. A template vm is pre-created
   and saved. Later vm is just a clone of the template vm so that they
   readonly share a portion of initial memory (including kernel, initramfs
   and the kata agent). CPU and memory are hot plugged when necessary.
3. cache: vm is created via vm caches. A set of cached vm are pre-created
   and maintained alive. New vms are created by just picking a cached vm.
   CPU and memory are hot plugged when necessary.

Fixes: #303
