The API returns an invalid error message, if an unknown field name is specified in the params of the simple query

[Ildiko Vancsa]

If the following simple query is sent to the API:
q=[{'field': 'non_valid_key',
    'op': 'lt',
    'value': 42}]

the following error message is received:
u"Invalid input for field/attribute op. Value: 'lt'. unimplemented operator for non_valid_key"

instead of:
u'Unknown argument: "non_valid_key": unrecognized field in query: [<Query u\'non_valid_key\' lt u\'42\' None>], valid keys: set([\'resource\', \'end\', \'start\', \'metaquery\', \'end_timestamp_op\', \'meter\', \'project\', \'source\', \'user\', \'start_timestamp_op\', \'message_id\'])'

    Fix validation error for invalid field name in simple query

    The field name validation code runs only in case of the operator that is
    specified for the invalid field name, is 'eq'. Otherwise the validation
    ends with an invalid operator error. The field name validation code was
    modified to check the field name first and only checks the operators for
    valid field names.
