Avoid unnecessary reloads generating lua_shared_dict directives

[aledbf]

What this PR does / why we need it:

Running the controller with --v=2 the lua_shared_dict order changes and forces a reload

-	lua_shared_dict configuration_data 20M;
-	lua_shared_dict certificate_data 20M;
-	lua_shared_dict balancer_ewma 10M;
 	lua_shared_dict balancer_ewma_last_touched_at 10M;
 	lua_shared_dict balancer_ewma_locks 1M;
 	lua_shared_dict certificate_servers 5M;
+	lua_shared_dict configuration_data 20M;
+	lua_shared_dict certificate_data 20M;
+	lua_shared_dict balancer_ewma 10M;

Which issue this PR fixes (optional, in fixes #<issue number>(, fixes #<issue_number>, ...) format, will close that issue when PR gets merged): fixes #
