API-client: remove unused ContainerListOptions.Quiet field

This option was originally added in d05aa418b0466553a24d42896f99176cfa29765f,
and moved in 8b15839ee85b291266d07f97d9ad6ca0326d1339 (after which it temporarily
went to the docker/engine-api repository, and was brought back in this repository
in 91e197d614547f0202e6ae9b8a24d88ee131d950).

However, it looks like this field was never used; the API always returns the standard
information, and the "--quiet" option for `docker ps` is implemented on the CLI
side, which uses different formatting when setting this option;

This patch removes the unused field,
