Refactor the compose ps command flagging process

[HanquanHq]

What is the problem you're trying to solve

According to #1680, I want to refactor the compose ps command flagging process. Since #1702 is marked invalid, I open this issue for tracking purposes.

Describe the solution you'd like

1. Create a file in pkg/api/types/${cmd}_types.go, and define the CommandOption for this command
2. Create some file in pkg/api/cmd/${cmd}, and move the command entry point in real into this package
3. Create new docs in docs/reference/api/${cmd}_types.md, and describe the field in CommandOption

Additional context
