Add support for recent Sensu features

[calebhailey]

Compare the output of sensuctl describe-type all with the resources we have support for managing via the cookbook.

As of 6.0.0, the types are as follows:

authentication/v2.Provider types will be fully supported by 3 custom resources once #81 is closed

[webframp]

I'm not sure it makes much sense to manage Silenced, LicenseFile and APIKey types via chef resources, but I can test a few ideas if that is really needed by users.

My thinking for license is: It's unique per user and possibly sensitive data, api key is definitely sensitive and unique GUID per api key. Silenced should be an ad-hoc item created using sensuctl and not a chef resource in most cases that I can think of.

@calebhailey if you have ideas or feedback for these types let me know.

[webframp]

Also question the value of a sensu_event custom resource. Should scope it's usage to a few user stories in some way since an Event in sensu can be a pretty complex composite type.

[webframp]

As mentioned earlier: Silenced, LicenseFile, APIKey and Event types are odd candidate to manage via chef resources so they've been skipped for now.

If there are user needs to have these as chef resources they can definitely be worked on in the future.
