Fixed - in 'manage cluster' tab, if user click on 'delete' icon, not only the DB entries will be removed, but also the same function of 'clean cluster' in the 'deploy' tab will be executed.  During uninstall, the same logs that are currently shown in the text box in 'deploy' tab will show in a pop up window.
Added Next & Prev Functionality
Fixed - Remove old instance of cluster if user clicks "Start deployment twice"
