ORADB: Installation using pre-extracted directory structure

When the Oracle DB ZIP files are stored in a network location, such as NFS, it may be advantageous for Puppet to use a pre-extracted directory structure rather than unzip the files every time. This removes unnecessary writes to storage and dramatically decreases the overall database installation time.

How to use this:
Set the new boolean $zipExtract to false. This tells Puppet that it will use a pre-extracted directory structure rather than ZIP files. The default is true, use ZIP files.
Example:    zipExtract => false,

As Puppet no longer transfers or uses any ZIP files, defining $puppetDownloadMntPoint isn't necessary.
Example:    puppetDownloadMntPoint => undef,

Set $downloadDir to the directory containing the pre-extracted directory structure. 
Example:    downloadDir => '/nfs/oracle/installer/11.2.0.3',
