…while server shutdown https://perconadev.atlassian.net/browse/PS-9611 Changed max value of the 'masking_functions.dictionaries_flush_interval_seconds' variable: instead of 'ULLONG_MAX' we now limit it to 60 * 60 * 24 * 365 seconds = 31 536 000 seconds (1 year). Improved 'is_terminated_lambda' in the 'dictionary_flusher_thread' - we now also check for additional server termination conditions. Improved how 'dictionary_flusher_thread' reloads cache - before executing dictionary table SELECT, we now always reset diagnostic area in THD object to an empty state. Added new 'enable_masking_functions_flush_thread_turbo_mode' DBUG option which helps to simulate continuous (without delays) cache reload. Added new 'component_masking_functions.flusher_thread_da_cleanup' MTR test case which simulates the scenario reported in the bug description. Added new checks to the 'component_masking_functions.sys_var_dictionaries_flush_interval_seconds_basic' MTR test case - we now check for min and max values of the 'dictionaries_flush_interval_seconds' variable.
