[suhyenim]

What this PR does / why we need it:

This PR is a follow-up to PR #706, #722 and implements phase 4 of issue #709.

It enhances instrumentation coverage by adding span attributes and provides more detailed trace information for better observability.

The image below shows the result after running the pod-delete experiment as an example.

The span attribute in the PR is created based on two conditions:

1. A supplementary explanation for the span
2. The value remains unchanged during the span

The following tables summarize the span attributes:

Experiment, Helper, Probe, Fault

category	span attributes
experiment	experiment.name, experiment.ramptime
helper	helper.name, helper.pod.name, helper.image.name
probe	probe.phase, probe.name, probe.type, probe.mode
fault	chaos.duration, chaos.interval, chaos.namespace
