Review docs for update items, identify/file issues

Review all of the docs on docs.couchbase.com for the SDK. Check for the following:

1. Are there any leftover parts that are copied from SDK2 that need to be updated/immediately commented out?
2. Is the API reference pointing to the current version?
3. Is it generally complete with respect to the Docs SDK (particularly the outline)?

Subsequently, smaller groups will get together to prioritize what needs to be done, but of course fixing small things as you encounter them is fine.

Before filing an issue, please check to see if one already exists. The first place for this is a JIRA search, the other source for this is Docs for SDK 3.
