[Bug]: Panic on running the serve command about k8sgpt

[VaibhavMalik4187]

@JuHyung-Son, I've opened this issue to track #966 (comment). Looks like this problem was introduces by f2138c7. I've not found the root cause of the problem just yet but a quick fix is to change:
ServeCmd.Flags().BoolVarP(&enableHttp, "http", "h", false, "Enable REST/http using gppc-gateway") to ServeCmd.Flags().BoolVarP(&enableHttp, "http", "", false, "Enable REST/http using gppc-gateway")

Looks like the shorthand h defined for the http flag is having problems because the help flag also uses h as the shorthand.

yes there should be proper replacement character

ServeCmd.Flags().BoolVarP(&enableHttp, "http", "H", false, "Enable REST/http using gppc-gateway") works fine.

hmm giving capital letter looks awkward. like first suggest, let`s just not set shorthand.

Makes sense. I've opened a PR to address this issue.
