BUGFIX:

* In Consul UI, showing data from KV with markup was not properly handled

NEW FEATURES:

Support any request method for remote_resource.as_json (#41)

 - support post and other request methods
 - accept any 2xx result (instead of just 200). This is a semi-breaking
   change.
 - accept body passed for non GET requests
 - allow to add headers (such as Authorization)
