api: always enable retry_on_request
The current behavior makes by default retry_on_request does not work,
which is confusing. Nothing except the developer can raise a
RetryRequest, so there can not be any misunderstanding. Having to both
enable the switch *and* raise RetryRequest makes it more complicated
than it needs to be.
This patch simplifies the API by deprecating retry_on_request and
retry_on_request() decorator, enabling the exception everywhere
wrap_db_retry() is used.
