Shall we update the lint script and the format script as echo skipped for mgmt package with modular generation?

If we choose to skip it, we will probably need to skip it for both data plane and mgmt plane as Modular will be used in data plane in the future as well.

• Missing return type on function - We should fix
• 'p' is already declared in the upper scope on line - Not sure where this happen need to look the code
• _ prefixes. I think I will fix this in my current PR, I'm removing the _ and tracking internal files differently
• ts-doc issues - We should fix
• Don't use Function as a type - I think we'll have to ignore this
• the file does not have a correct copyright header - We should fix
• 'item' is never reassigned. Use 'const' instead - We should fix
