Adds support for Tiered Caching

[iveelsm]

This adds support for manipulation, creating and deletion of tiered cache settings through the existing mechanisms in the Cloudflare API. This adds support for settings generic and smart tiered cache topologies through the terraform provider.

Implementation:

• Create/Update, Delete and Get methods for Tiered Cache settings

Dependent on the merging of the cloudflare-go PR: cloudflare/cloudflare-go#1149

Once that PR is merged, this require additional updates to pull in the latest published version.

Closes #2100

couple of things:

• you'll need to also add this to the provider.go (see Create Total TLS Resource #1979 for an example) for this to actually work. the acceptance tests will fail as is at the moment even if you shim in cloudflare-go as the resource isn't defined.
• you can run make docs to generate the automatic documentation. this is also run on master merges but doing it now gives you a chance to check it all out before then.

other than that, looking good! i'll run the acceptance tests once the couple of things are addressed.

Word! Can do. I will probably get it fully ready once we merged the cloudflare-go PR.

if you'd like to work on them together, there is the option of doing https://github.com/cloudflare/terraform-provider-cloudflare/blob/master/contributing/development.md#pulling-in-unreleased-changes-from-go-library-cloudflare-go locally that allows you to get this 95% of the way there and just wait for the version bump to arrive in the mainline.
