* Add test for #4812: Autocomplete suggestions should have size limits
This test verifies that autocomplete suggestion maps enforce size limits
to prevent unbounded memory growth. The test calls setTablesForSchema()
and setQueriesForMod() methods that should enforce:
- Maximum 100 schemas in tablesBySchema
- Maximum 500 tables per schema
- Maximum 100 mods in queriesByMod
- Maximum 500 queries per mod
This test will fail until the size limiting implementation is added.

* Fix#4812: Add size limits to autocomplete suggestions maps
Implements bounded size for autocomplete suggestion maps to prevent
unbounded memory growth with large schemas:
- Added constants for max schemas (100) and max tables per schema (500)
- Created setTablesForSchema() and setQueriesForMod() methods that enforce
limits using LRU-style eviction when limits are exceeded
- Updated interactive_client_autocomplete.go to use the new bounded setter
This prevents excessive memory consumption when dealing with databases
that have hundreds of connections with many tables each.

- Execute RefreshConnections asyncronously
- Add connection_state table to indicate the loading state of connections
- Optimise RefreshConnections by cloning connection schemas
- Add locking to ensure only a single instance of RefreshConnections runs
- Start executing queries without waiting for connections to load, add smart error handling to wait for required connection
- Optimise autocomplete for high connection count
- Autocomplete and inspect data available before all conections are refreshed
- Update file watcher to respond to CHMOD, so thaat it pickes up deletion of file contents
