Added a userBaseDir parameter to oradb::installdb.pp

Hi,

We have NIS users and local users. By local convention, the NIS user home directories are in /home and local user home directories are in /localhome.

We would like to use the oradb module, but its assumption that the oracle user account is in /home/${user} causes problems because in our case, a global NIS oracle user already exists. Clearly this shouldn't really be the case, but it would be difficult to change that now.

So I propose a simple change to provide a user base directory parameter to installdb.pp which defaults to /home.

Thanks,

Simon.
