Enable History keys and Backspace key in VIOS

Answer

Many users familiar with Unix environments, and even PC command line environments, are acquainted with using the Up and Down arrow keys to bring up previous commands, as well as using the Left and Right arrow keys to move the cursor within the current command line.

These functions are not enabled by default in the VIOS command line environment. Additionally, the Backspace key is not enabled by default, in many cases. Users are frequently interested in knowing the current user and current working directory. While this is not specifically needed in most VIOS cases, it is still useful to know.
