*
Introduce
`connection.data_sources`
and
`connection.data_source_exists?`
.
These methods determine what relations can be used to back Active Record
models (usually tables and views).
Also deprecate `SchemaCache#tables`, `SchemaCache#table_exists?` and
`SchemaCache#clear_table_cache!` in favor of their new data source
counterparts.
