@keizer619 Please take a look

[NipunaMadhushan]

@Jaagrav We have discussed about this issue internally and decided to show only the version info for any command below.
bal version -h
bal --version -h
bal -v -h
bal version --help
bal --version --help
bal -v --help

We made this decision as it has been the norm in most of other languages.

Can you please update the PR according to the requirement I mentioned above?
