CPUSE Deployment Agent install script

[G_W_Albrecht]

After answering the Deployment Agent Update question, i had an idea to
write a script that handles killing and starting of processes as well as the rpm
installation itself. The process (lifted from sk92449) is as follows:

- unpack the DeploymentAgent_000001xxx_1.tgz file to get the CPda-00-00.i386.rpm
- transfer CPda-00-00.i386.rpm and the script daup.sh to any directory on the GAiA unit
- make daup.sh executable
- call ./daup.sh
- Log file daup.log now can be found in the same directory
