board/common: deprecate existing show command

There's several reasons for this. The main reason is that it was
developed as an intermediate way of getting system information when
the operational datastore was almost empty. There's not a lot of data
available in the operational datastore and we shall rely on that data
primarily. This command isn't safe to run from a jailed CLI as i
doesn't validate input and run commands directly in the shell, making
it hard to protect against a CLI jail break.

In upcoming patches we will introduce a new show tool that relies
solely on operational data and which sanitize the user input.
