This commit also improves some internal behavior related to the
bootstrap configuration generation, and deprecated some methods that
will be removed in upcoming versions.
* Removes all methods that return the bootstrap DataBag or the raw
configuration json to return the BootstrapConfig object instead.
* Deprecates all methods that provide support for old Chef versions.
* Formats the Enterprise Chef provider according to the jclouds
formatting guidelines.
* Deprecates the ChefContext view. That view is not an abstraction and
only provides access to the ChefService. It can be obtained from the
ChefApi itself.
Refactored the domain model to be immutable and addressed some
inconsistences with the Chef Server API model.
Removed all HEAD methods, as they have been removed from newer versions
of Chef. They were used to test the existance of a given resource, and
with newer versions the only way to do that is via a GET operation.
Now all live tests are passing for Community Chef 0.10.8, 11.0.6 and
Enterprise Chef.
