Rob Crittenden 58746226d4 Use the Output tuple to determine the order of output
The attributes displayed is now dependant upon their definition in
a Param. This enhances that, giving some level of control over how
the result is displayed to the user.

This also fixes displaying group membership, including failures of
adding/removing entries.

All tests pass now though there is still one problem. We need to
return the dn as well. Once that is fixed we just need to comment
out all the dn entries in the tests and they should once again
pass.

class Output(ReadOnly):
"""
Simple description of a member in the return value ``dict``.
This class controls both the type of object being returned by
a command as well as how the output will be displayed.
For example, this class defines two return results: an entry
and a value.
>>> from ipalib import crud, output
>>> class user(crud.Update):
...
... has_output = (
... output.Entry('result'),
... output.value,
... )
The order of the values in has_output controls the order of output.
If you have values that you don't want to be printed then add
``'no_display'`` to flags.
The difference between ``'no_dipslay`` and ``'no_output'`` is
that ``'no_output`` will prevent a Param value from being returned
at all. ``'no_display'`` will cause the API to return a value, it
simply won't be displayed to the user. This is so some things may
be returned that while not interesting to us, but may be to others.
>>> from ipalib import crud, output
>>> myvalue = output.Output('myvalue', unicode,
... 'Do not print this value', flags=['no_display'],
... )
>>> class user(crud.Update):
...
... has_output = (
... output.Entry('result'),
... myvalue,
