Description of problem:
Currently, there are a number of places where Y/N questions are asked.  The
general format that I've seen is "Question... (Y/n)?  In most situation, the
capital letter is the default should no input be given.  This is not working as
expected in the couple places I've noticed.  See Additional Info for places
that I've noticed.  

Version-Release number of selected component (if applicable):
5.4-2.0.99.8.3

How reproducible:
Always

Steps to Reproduce:
1. Go through actions to get to a Y/N question
2. Note which is capitalized
3. hit Enter without any input

Actual results:
Question is repeated

Expected results:
Default should be used

Additional info:
This issue was seen at
1.  Apply storage configuration
2.  Local Install and Reboot

A standard function might be the way to go to solve this.  In both of the cases
above, the Y is the apparent default option.  I would think that either we want
no default and require an answer (which is the current functionality) or
default to N.
