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.

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.

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.

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.

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`.

It disconnects the agent connection and removes the sandbox
from global sandbox list.
A new option `LongLiveConn` is also added to kata
agent's configuration. When set, the API caller is expected
to call sandbox.Release() to drop the agent connection explicitly.
`proxyBuiltIn` is moved out of agent state because we can always
retrieve it from sandbox config instead.

Because of the bad design of the cc_proxy_mock go routine, we were
leaving an infinite loop running into this go routine behind. This
was consuming a lot of resources and it was obviously slowing down
the tests being run in parallel. That's one of the reason we were
hitting the 10 seconds timeout when running go tests.

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.
