(maint) - Adding java_ks to be managed as a Windows module

[pmcmaw]

Currently java-ks is only listed as a Linux module. It is actually
cross-platform therefore adding Windows to it. This will allow java_ks
to make use of files such as appveyor.yml

[pmcmaw]

@glennsarti added you as a reviewer as I would like to get someone with a Windows background to make sure the team is ok with this

[glennsarti]

You may want to do a modsync run on java_ks just to see what happens, as I think this does more than just add appveyor...

[pmcmaw]

Ahh cool, I will have a look at that @glennsarti

[pmcmaw]

So yeah @glennsarti your right it changes a lot more than adding the appveyor config. The following is also changed:

1. Gemfile
2. appveyor.yaml
3. default nodeset

Closing this PR.

[pmcmaw]

After going through a 'dry' run, the above config file changes are fine.

Test results in both Appveyor and Travis are not affected and the builds continue to pass with no worrying or significant changes. Reopening and continuing to add to modulesync as long as you have no objections @glennsarti

This is an example of the changes made by modulesync: https://github.com/puppetlabs/puppetlabs-java_ks/pull/202/files

I manually changed the .sync.yml but if we were to go ahead I will get that change put into the module rather than here.

LGTM - The title still says WIP otherwise I would've merged.
