.SYNOPSIS
    Perform power actions on esxi
.DESCRIPTION
    When we poweroff, shutdown, reboot a host we need to provide a reason to do so. This is especially
    boring and time consuming if you have a lot of hosts on which you have to do this. This is to ease
    that pain. It has 4 options to choose from
     A. Enter Maintenance Mode
     B. Exit Maintenance Mode
     C. Shutdown
     D. Reboot 
    It will ask the reason to perform that action and it will input that reason before it performs the 
    chosen action.
