help for immu client

[ghost]

I should be able to run the following command:

./immu --help zscan

and get detailed help about the command.

When I type a command in a wrong way I should get correct information. Fow example, as it is no:

immudb git:(master) ✗ ./immu zscan
Error: accepts 1 arg(s), received 0
Usage:
  immu zscan set [flags]
Aliases:
  zscan, zscn
Flags:
  -a, --address string   bind address (default "127.0.0.1")
  -h, --help             help for zscan
  -p, --port int         port number (default 3322)

from this I understand that zscan is run alone with no argument and some flags: immu zscan set [flags], which is wrong.

Of course, this should be done for all commands.

1. It’s ./immu zscan —help.
2. Mandatory params are not surrounded by any brackets, optional ones are surrounded by square brackets in help output. So in immu zscan set [flags] the first mandatory arg is set.

Let's do as in man pages. Qquare brackets for optionals and no brackets for required, but let's change the name of set to mean the set name.
