Rahim Kanji	aaa959d024	Refactor and optimize read-only actions method ... This commit optimizes the read-only actions method by removing the dependency on proxysql admin tables.

Javier Jaramago Fernández	3c086fe95b	Fix GR servers reconfiguration due to SHUNNED writer ... When writer was set as SHUNNED due to replication lag, and 'mysql_servers' table was regenerated (via servers reconfiguration or other action).

René Cannaò	36575d273a	Several code improvements ... In Admin: - replaced a lot of flush_[...]__from_memory_to_disk() and flush_[...]__from_disk_to_memory() with a generic flush_GENERIC__from_to() - several commands like "LOAD MYSQL SERVERS FROM DISK" and similar are automatically generated for various modules (not all) and saved/map in a map load_save_disk_commands - FlushCommandWrapper() is able to map the various LOAD/SAVE from/to DISK into commands to run on SQLite	3 years ago
