> Custom attributes are allowed at field level as per Avro specification : [https://avro.apache.org/docs/current/spec.html#schemas|https://www.google.com/url?q=https://avro.apache.org/docs/current/spec.html%23schemas&sa=D&source=buganizer&usg=AOvVaw3JfXMgFX6Eq0Fd0TjDzgb1] 
> But Avro c++ implementation does not support custom attribute at field level.
> e.g. following schema cannot be parsed correctly due to presence of "sqlName" attribute.
> {
>     'doc': 'weather warning',
>     'name': 'weather',
>     'type': 'record',
>     'fields': [
>     {
>         'name': 'station',
>         'type':'string',
>         'sqlName':'abc-@12'
>     },
>     {
>         'name': 'time',
>         'type':'long',
>         'sqlName': '用户名'
>     }]
> }
> Update implementation to support custom attribute at field level.
