Timescaledb: 0.10.1 Release

High-level changes * Improved memory management for long-lived connections. * Fixed handling of dropping triggers that would lead to orphaned references in pg_depend. * Fixed pruning in CustomScan when the subplan is not a Scan type that caused a crash with LATERALs. * Corrected size reporting that was not accurately counting TOAST size * Updated error messages that more closely conform to PG style. * Corrected handling of table and schema name changes to chunks; TimescaleDB metadata catalogs are now properly updated

Notable commits * [8b58500] Fix bug where dropping triggers caused dangling references in pg_depend, disallow disabling triggers on hypertables * [745b8ab] Fixing CustomScan pruning whenever the subplan is NOT of a Scan type. * [67a8a41] Make chunk identifiers formatting safe using format * [41af6ff] Fix misreported toast_size in chunk_relation_size funcs * [4f2f1a6] Update the error messages to conform with the style guide; Fix tests * [3c28f65] Release cache pin memory * [abe76fc] Add support for changing chunk schema and name
