Do not do extra search for ipasshpubkey to generate fingerprints
    
    Host, user and idview commands do unnnecessary extra search for
    ipasshpubkey attribute to generate fingerprints.
    
    Note: Host and user plugins shows ipasshpubkey only when the attribute
    is changed, idviews show ipasshpubkey always. This behavior has been
    kept by this commit.
    
    common_pre/post_callbacks were fixed in [base|stage]user modules.
    common_callbacks requires the same arguments as pre/post_callbacks now
    (except baseuser_find.post_common_callback)
    
    Note2: in *-add commands there is no need for managing ipasshpubkey as
    this attribute should be shown always there.
