- add a reference Dockerfile to tools
- update kata-monitor build to:
1) utilize the kata buildflags, which were dropped before
2) disable CGO, so we have option for building in alpine
From root of the repository, example build:
$ docker build -f tools/packaging/kata-monitor/Dockerfile -t kata-monitor .

Update cloud-hypervisor to commit 2706319.
Fixes a limitation in OpenAPITools/openapi-generator tool,
it's impossible to send go zero types, like false and 0 to
cloud-hypervisor because `omitempty` is added if a field is not
required.

Make `asset.go` the arbiter of asset annotations by removing all asset
annotations lists from other parts of the codebase.
This makes the code simpler, easier to maintain, and more robust.
Specifically, the previous behaviour was inconsistent as the following
ways:
- `createAssets()` in `sandbox.go` was not handling the following asset
annotations:
- firmware:
- `io.katacontainers.config.hypervisor.firmware`
- `io.katacontainers.config.hypervisor.firmware_hash`
- hypervisor:
- `io.katacontainers.config.hypervisor.path`
- `io.katacontainers.config.hypervisor.hypervisor_hash`
- hypervisor control binary:
- `io.katacontainers.config.hypervisor.ctlpath`
- `io.katacontainers.config.hypervisor.hypervisorctl_hash`
- jailer:
- `io.katacontainers.config.hypervisor.jailer_path`
- `io.katacontainers.config.hypervisor.jailer_hash`
- `addAssetAnnotations()` in the `oci` package was not handling the
following asset annotations:
- hypervisor:
- `io.katacontainers.config.hypervisor.path`
- `io.katacontainers.config.hypervisor.hypervisor_hash`
- hypervisor control binary:
- `io.katacontainers.config.hypervisor.ctlpath`
- `io.katacontainers.config.hypervisor.hypervisorctl_hash`
- jailer:
- `io.katacontainers.config.hypervisor.jailer_path`
- `io.katacontainers.config.hypervisor.jailer_hash`
This change fixes the bug where specifying a custom hypervisor path via an
asset annotation was having no effect.

bindmount remount events are not propagated through mount subtrees,
so we have to remount the shared dir mountpoint directly.
E.g.,
```
mkdir -p source dest foo source/foo
mount -o bind --make-shared source dest
mount -o bind foo source/foo
echo bind mount rw
mount | grep foo
echo remount ro
mount -o remount,bind,ro source/foo
mount | grep foo
```
would result in:
```
bind mount rw
/dev/xvda1 on /home/ubuntu/source/foo type ext4 (rw,relatime,discard,data=ordered)
/dev/xvda1 on /home/ubuntu/dest/foo type ext4 (rw,relatime,discard,data=ordered)
remount ro
/dev/xvda1 on /home/ubuntu/source/foo type ext4 (ro,relatime,discard,data=ordered)
/dev/xvda1 on /home/ubuntu/dest/foo type ext4 (rw,relatime,discard,data=ordered)
```
The reason is that bind mount creats new mount structs and attaches them to different mount subtrees.
However, MS_REMOUNT only looks for existing mount structs to modify and does not try to propagate the
change to mount structs in other subtrees.

In cloud-hypervisor, it provides a single unified way of unplugging
devices, e.g. the `/vm.RemoveDevice` HTTP API. Taking advantage of this
API, we can simplify our implementation of `hotplugRemoveDevice` in
`clh.go`, where we can consolidate similar code paths for different
device unplug (e.g. no need to implement `hotplugRemoveBlockDevice` and
`hotplugRemoveVfioDevice` separately). We will only need to retrieve the
right `deviceID` based on the type of devices, and use the single
unified HTTP API for device unplug.
