In order to choose if the network monitor should be used or not, this
patch makes it configurable from the configuration.toml file.

23a35c84c9 kata-env: Fix display of debug options
The runtime and hypervisor `Debug` options were always showing as
`false` (although all debug options in `configuration.toml` were
correctly honoured).

Note: Also moved location of `FactoryConfig` in `RuntimeConfig` as the
`malign` linter was complaining:

```
virtcontainers/pkg/oci/utils.go:102:20⚠️ struct of size 408 could be 400 (maligned)
```

Fixes #724.

ce288652d5 virtcontainers: remove sandboxConfig.VMConfig
We can just use hyprvisor config to specify the memory size
of a guest. There is no need to maintain the extra place just
for memory size.

9c6ed93f80 hook: Move OCI hooks handling to the CLI
The CLI being the implementation of the OCI specification, and the
hooks being OCI specific, it makes sense to move the handling of any
OCI hooks to the CLI level. This changes allows the Kata API to
become OCI agnostic.

Fixes #599

44d2ec757c virtcontainers: network: Rename CNM to DefaultNetwork
Since we removed the CNI implementation and that we agreed the network
should only be handled in a single way from virtcontainers, this patch
logically replace the "CNM" naming with "Default".

58448bbcb8 logging: Allow SetLogger to be called multiple times
Now that the `SetLogger()` functions accept a `logrus.Entry`, they can
access the fields that have already been set for the logger and
re-apply them if `SetLogger()` is called multiple times.

This fixes a bug whereby the logger functions -- which are necessarily
called multiple times [1] -- previously ended up applying any new fields
the specified logger contained, but erroneously removing any additional
fields added since `SetLogger()` was last called.

Partially fixes #519.

0309e59cf8 cli: add vm factory management subcommand
Add enable_template option to the config file.
When it is set, enable the vm template factory.

cache factory cannot be used by kata cli directly because
it requires a running daemon to maintain the cache VMs.

`kata-runtime factory init` would initialize the vm factory and
`kata-runtime factory destroy` would destroy the vm factory.

When configured, a vm factory is loaded before creating new sandboxes.

4d470e513b shm: Create shared /dev/shm
This commit checks the size of "/dev/shm" for the sandbox container
which is then used to create the shared memory inside the guest.
kata agent then uses this size to set up a sandbox level ephemeral
storage for shm. The containers then simply bind mount this sandbox level
shm.

With this, we will now be able to support docker --shm-size option
as well have a shared shm within containers in a pod, since they are
supposed to be in the same IPC namespace.

366558ad5b virtcontainers: refactor device.go to device manager
Fixes #50

This is done for decoupling device management part from other parts.
It seperate device.go to several dirs and files:

```
virtcontainers/device
├── api
│   └── interface.go
├── config
│   └── config.go
├── drivers
│   ├── block.go
│   ├── generic.go
│   ├── utils.go
│   ├── vfio.go
│   ├── vhost_user_blk.go
│   ├── vhost_user.go
│   ├── vhost_user_net.go
│   └── vhost_user_scsi.go
└── manager
    ├── manager.go
    └── utils.go
```

* `api` contains interface definition of device management, so upper level caller
should import and use the interface, and lower level should implement the interface.
it's bridge to device drivers and callers.
* `config` contains structed exported data.
* `drivers` contains specific device drivers including block, vfio and vhost user
devices.
* `manager` exposes an external management package with a `DeviceManager`.

6107694930 runtime: rename pod to sandbox
As agreed in [the kata containers API
design](https://github.com/kata-containers/documentation/blob/master/design/kata-api-design.md),
we need to rename pod notion to sandbox. The patch is a bit big but the
actual change is done through the script:
```
sed -i -e 's/pod/sandbox/g' -e 's/Pod/Sandbox/g' -e 's/POD/SB/g'
```

The only expections are `pod_sandbox` and `pod_container` annotations,
since we already pushed them to cri shims, we have to use them unchanged.
