UpdateUninstallModules.ps1

#Works in parallel. However Update and uninstall verbosity aren't in sequence. I want it to wait till Azmodule update completes and uninstall child modules in one go.
#Test on Terminal.
#Remove Scope and parallel while running on PS5.1.
#Ran sucessfully in updating. However, didn't uninstall. Had to run again. Add '-Wait' parameter so it waits till update finishes to uninstall
