Storage of recordings

If you supply a URL in the data portion of the callflow, Kazoo will send an HTTP PUT with the recording to the URL when the recording has finished.

If you omit the URL, there are a couple options for storage:

Check system_config/media for the store_recordings boolean()
- If false, no storage will occur
- If true, check system_config/media for third_party_bigcouch_host
  - If undefined, store to the Kazoo BigCouch cluster
  - If defined, send the recording to the configured URL
