docs: add missing "quiet" parameter for image/load and update response

Progress reporting during image load was added
in 415dd8688618ac2b3872c6a5b5af3afcef2c3e10, but
the corresponding query-parameter was not documented
in the API docs.

This updates the API docs, and adds a response example
both with quiet enabled and disabled.

 * `GET /containers/(id or name)/logs` now accepts a `details` query parameter to stream the extra attributes that were provided to the containers `LogOpts`, such as environment variables and labels, with the logs.
