add plugin support

[bilsch]

hiera config to add / remove plugins also works

kibana::plugins:
marvel:
source: elasticsearch/marvel/latest

And to remove

kibana::plugins:
marvel:
source: elasticsearch/marvel/latest
ensure: absent

I'll work on getting the test suites added for this shortly

[bilsch]

This should be ready for review. Let me know if you want more test cases added in

@jlambert121 mind taking a look at this?

[jlambert121]

This looks great - thanks! Would you add a test for removing a plugin and squish things down to a single commit and I'll merge it?

[bilsch]

@jlambert121 ok tweaked the rspec tests and added the remove / absent test and squished to a single commit

[jlambert121]

Thanks!
