Integrate commands for making outputs

[sj-aws]

There are multiple commands for making some outputs: show, status, record, and fmt_json. Let's integrate those into one command (probably show) for simplicity.

This will also helps supporting yaml-format DAMON parameters formatting[1]. For example,

# damo show damon_params --format json
# damo show damon_params --format yaml

Actually, nearly every damo commands except DAMON controlling (start/stop/tune) are somewhat for making some output. Maybe further categorizing is better...

Now, the plan is to replace old workflow for collecting data and visualizing. For this, we will introduce three new commands.

• collect: Collect DAMON outputs and system status
• read: Visualize the collected data
  • Can do the collecting of the data itself, for convenient usage.
  • Aims to replace show, status, and report.
  • The name may better to be changed.
• args: Generate complex arguments for other commands
  • Such as DAMON parameters and snapshot formatting parameters (--format_region of damo show)
  • Aims to replace fmt_json and support yaml format DAMON parameters

args command is added with support of json and yaml format DAMON parameters generation. The commit for yaml format support is d481e66

After 2024-09-05, we will[1] use damonitor repo[2] as the only main repo for GitHub. To continue discussion of this issue on the repo, I just created a new issue[3] there. Please use the new issue for followup discussions.

Closing this issue in favor of the new one on the damonitor repo. Please ask me to open this again if you cannot continue the discussion from the new issue.
