Additional Interface Cleanup

[korgon]

With the move to 1.0 we need to ensure our external interfaces are in a good state. Some interfaces that could use work are listed below and they are all pretty related; there may be more interfaces that could use adjusting.

Client

The autocomplete, search, finder and recommend methods return multiple API results, but they do it differently - we should be consistent with the response format. I am leaning more towards returning an object with the different response data but we could stick with the Promise.all array format as well - either way consistency is important here.

// possible `search` return obj
{
  search: SearchResponse,
  meta: MetaResponse
}

// possible `recommend` return obj
{
  recommend: SearchResponse,
  meta: MetaResponse
  profile: ProfileResponse
}

MockClient

Changes to the Client above would necessitate changes to the Mock for it.

MockData

Similarly to the MockClient changes to MockData would be necessary, as currently the meta response is added into the API response - we would want to clean this up.

Controller search methods

Changes to all of the above would necessitate changes to the controller search methods as well as the associated store update methods; these would need to be refactored to separate out multiple API responses instead of merging them.
