The API defines a default limit for searches, but when removing the
default from the cli, the client still sends "0" as a limit, which
is not allowed by existing versions of the API:
docker search --limit=0 busybox
Error response from daemon: Limit 0 is outside the range of [1, 100]
This patch changes the client so that no limit is sent if none was set ("0"),
allowing the daemon to use its (or the registry's) default.
