Subject: Provide a be_get_account_info_send function
In order to resolve group names in the simple access provider we need to
contact the Data Provider in a generic fashion from the access provider.
We can't call any particular implementation (like sdap_generic_send())
because we have no idea what kind of provider is configured as the
id_provider.
This patch splits introduces the be_file_account_request() function into
the data_provider_be module and makes it public.
A future patch should make the be_get_account_info function use the
be_get_account_info_send function.
(cherry picked from commit b63830b142053f99bfe954d4be5a2b0f68ce3a93)
