Clean up the table schema to get rid of legacy tables and functionality that makes it more difficult to provide an upgrade path. Notable changes: * Get rid of legacy tables and code * Simplify directory structure for SQL code * Simplify table hierarchy: remove root table and make chunk tables * inherit directly from main table * Change chunk table suffix from _data to _chunk * Simplify schema usage: _timescaledb_internal for internal functions. * _timescaledb_catalog for metadata tables. * Remove postgres_fdw dependency * Improve code comments in sql code
