MINOR: cli: apply the fuzzy matching on the whole command instead of words

Browse Source 
Now instead of comparing words at an exact position, we build a fingerprint
made of all of them, so that we can check for them in any position. For
example, "show conn serv" finds "show servers conn" and that "set servers
maxconn" proposes both "set server" and "set maxconn servers".
