Allow version targeting and auto-upgrading

[smerchek]

Currently, the package is only installed once. If new versions are present, they are not installed. There is also no way to force an upgrade with this module.

It should be possible to pass through the ensure setting as specified in the Puppet Documentation.

This will allow a specific version like 7u55-0~webupd8~1 (see http://www.ubuntuupdates.org/package/webupd8_java/precise/main/base/oracle-java7-installer for a list of versions).

Example Usage

class { 'java7':
   ensure => '7u55-0~webupd8~1',
}

The default should be installed to maintain backwards compatibility. It is also not desirable to auto-update java as there can often be breaking changes.

Unfortunately, this is not as easy as it seems. The webupd8 PPA only keeps the latest version of the package (they are considered "superseded"). So, if you try to specify an older version, you will get the error E: Version '7u55-0~webupd8~0' for 'oracle-java7-installer' was not found.

It seems to only solution to allow specific version targeting is to host an apt repository that or PPA that does not remove old versions.
