We aim (#12642) to use the schema commit log for raft tables. Now they are loaded at the first call to init_system_keyspace in main.cc, but the schema commitlog is only initialized shortly before the second call. This is important, since the schema commitlog initialization (database::before_schema_keyspace_init) needs to access schema commitlog feature, which is loaded from system.scylla_local and therefore is only available after the first init_system_keyspace call. So the idea is to defer the loading of the raft tables until the second call to init_system_keyspace, just as it works for schema tables. For this we need a tool to mark which tables should be loaded in the first or second phase. To do this, in this patch we introduce system_table_load_phase enum. It's set in the schema_static_props for schema tables. It replaces the system_keyspace::table_selector in the signature of init_system_keyspace. The call site for populate_keyspace in init_system_keyspace was changed, table_selector.contains_keyspace was replaced with db.local().has_keyspace. This check prevents calling populate_keyspace(system_schema) on phase1, but allows for populate_keyspace(system) on phase2 (to init raft tables). On this second call some tables from system keyspace (e.g. system.local) may have already been populated on phase1. This check protects from double-populating them, since every populated cf is marked as ready_for_writes.
