Make all `short` descriptions of commands start with capitalized letters

[vieiralucas]

It is currently inconsistent, some commands start with capital letters other not.
We should make sure all commands short descriptions start with capitalized letters.

This should be a pretty easy one, just search the codebase for the words.
They will all be inside cli/<command>.go
Just update the Short field of each command to have the letters capitalized.
