Define a common format for logs in Hyperlight

[dblnz]

At the moment, Hyperlight logs do not have a set format to follow and this leads to confusion when following logs.
It would be best to define a common format that all the internal logs in Hyperlight should follow to have a consistent approach.

Consider structured logging.

To correctly identify each sandbox in an environment running multiple sanboxes, we should generate a UUID for each sandbox and link the logs/traces to the specific ID.
This way it makes it simpler to follow and filter logs in a concurrent system.

Furthermore, we should define a common format for the logs generated inside hyperlight.
Maybe starting from something like sandbox=<UUID> message="something" and building on top of it to add other fields to make it simpler to grep/filter afterwards.

Yes , we should call this correlation_id, I think the challenge is how we propagate this value
