d314e2d0b7 agent: clean up share path created by the agent
The agent code creates a directory at
`/run/kata-containers/shared/sandboxes/sbid/` to hold shared data
between host and guest. We need to clean it up when removing a sandbox.

b05dbe3886 runtime: Convert to the new internal types package
We can now remove all the sandbox shared types and convert the rest of
the code to using the new internal types package.

This commit includes virtcontainers, cli and containerd-shim changes in
one atomic change in order to not break bisect'ibility.

20f2d30ab8 virtcontainers: share the agent's client between factory's VM and sandbox
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.

7bf84d05ad types: Replace agent/pkg/types with virtcontainers/pkg/types
This commit replaces every place where the "types" package from the
Kata agent was used, with the new "types" package from virtcontainers.

In order to do so, it introduces a few translation functions between
the agent and virtcontainers types, since this is needed by the kata
agent implementation.

309dcf9977 vendor: Update the agent vendoring based on pkg/types
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.

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.

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.
