databases/p5-DBIx-DisconnectAll: Add p5-DBIx-DisconnectAll 0.03

DBIx::DisconnectAll is utility module to disconnect all connected databases.

DBI has DBI->disconnect_all methods, but some DBD modules does not support it,
so DBI->disconnect_all is undocumented yet and unusable.

DBIx::DisconnectAll realizes disconnect_all from DBI's public API.
