If a file/directory doesn't exist, os.Stat() returns an
error. Assert the returned value with os.IsNotExist() to
prevent it from failing.

Removes custom trace functions defined across the repo and creates
a single trace function in a new katatrace package. Also moves
span tag management into this package and provides a function to
dynamically add a tag at runtime, such as a container id, etc.
Fixes#1162

Span attributes (tags) are not consistent in runtime tracing, so
designate and use core attributes such source, package, subsystem, and
type as span metadata for more understandable output.
Use WithAttributes() during span creation to reduce calls to
SetAttributes().
Modify Trace() in katautils to accept slice of attributes so multiple
functions using different attributes can use it.

we can have the following case,
1. start kata container with factory feature, this need kata-runtime
config to enable factory and use initrd as base image.
2. start a kata container.
3. cd /root; cd /run/vc/vm/template dir, this will make
/run/vc/vm/template to be in used.
4. destroy vm template with kata-runtime factory destroy , and check
the template mountpoint.
we can see the template mountpoints will add everytime we repeat the above steps .
[root@centos1 template]# mount |grep template
[root@centos1 template]# docker run -ti --rm --runtime untrusted-runtime --net none busybox echo
[root@centos1 template]# cd /root; cd /run/vc/vm/template/
[root@centos1 template]# /kata/bin/kata-runtime factory destroy
vm factory destroyed
[root@centos1 template]# mount |grep template
tmpfs on /run/vc/vm/template type tmpfs (rw,nosuid,nodev,relatime,seclabel,size=2105344k)

It turns out we have managed to break the static checker in many
difference places with the absence of static checker in github action.
Let's fix them while enabling static checker in github actions...

Modify calls in unit tests to use context since many functions were
updated to accept local context to fix trace span ordering.
Fixes#1355
Signed-off-by: Chelsea Mafrica <chelsea.e.mafrica@intel.com>
A significant number of trace calls did not use a parent context that
would create proper span ordering in trace output. Add local context to
functions for use in trace calls to facilitate proper span ordering.
Additionally, change whether trace function returns context in some
functions in virtcontainers and use existing context rather than
background context in bindMount() so that span exists as a child of a
parent span.

With kata containers moving to 2.0, (hybrid-)vsock will be the only
way to directly communicate between host and agent.
And kata-proxy as additional component to handle the multiplexing on
serial port is also no longer needed.
Cleaning up related unit tests, and also add another mock socket type
`MockHybridVSock` to deal with ttrpc-based hybrid-vsock mock server.
