Issue #116 Show banner when installing packages using `yum`

[gbraad]

Deals with #116

• It shows unsupported when trying to install
• Waits for confirmation before executing the actual yum command
• Allows confirmation to be overwritten by using -y in the command

Note: Banner might need to be more prominent...

@praveenkumar livecd-creator seems to interpret the $@ and $answer, and writes "" to the livecd filesystem.

@gbraad we need to make change to rhel template also because we want this for RHEL iso too right?

[gbraad]

I would like to, but can not make this call. As I remember developer tools do not follow the same support anyways. /cc: @LalatenduMohanty

[LalatenduMohanty]

@gbraad @praveenkumar Agree, we need to change RHEL ISO also.

[gbraad]

RHEL

done...

[gbraad]

This includes #123, so if rebasing... that PR should go first

[LalatenduMohanty]

@gbraad Please fix the merge conflict.

[gbraad]

We need to confirm the link first, before able to merge. Don't want to do 2 pushes to get this done.

Right. First we need https://docs.openshift.org/latest/minishift/using/troubleshooting.html#install-additional-software-not-supported to be up i.e. https://github.com/minishift/minishift/issues/1152

Test with RHEL ISO and worked as exected

$ ./minishift ssh
[docker@minishift ~]$ sudo yum install vim

@praveenkumar also verify, although late, if yum install -y vim works. It should show the banner, but not show the continue prompt.
