GOBMCN2-38 - install-oracle.sh improvement

- log the output
- add dynamic inventory files not to use the hardcoded one
- option inventory-file to specify an inventory file instead of the default harcoded one
- add options to be able to choose only some of the 4 main steps: --check-instance --prep-host --install-sw and --config-db to be able to choose amongst these steps to be executed; if none is chosen, all the steps are executed as before
- a new debug option
- enable short version choice (18 => 18.0.0.0.0) the time we find a better and dynamic solution
- wrote the then on the same line as the if
