deployment: added install scripts and made adjustments to scripts

Added install script for 'apt' and 'yum' based systems. Made the
necessary adjustments to the post-install.sh and post-update.sh scripts
for it to work on those systems.
deployment: updated install scripts for vhost usage

Updated the install scripts to support an install with a vhost file.
When an user executes a clean install it will get an option to specify
the folder in which the application is installed. This will generate a
vhost file in which this is specified.
