createSharded

Creates a DefaultShardManagerBuilder with caches inferred from intents.

In addition to the DefaultShardManagerBuilder profile settings:

• The event manager is set to the (optional) CoroutineEventManager

• The intents are set to JDAService.intents.

• In addition to the default-configured cache flags, JDAService.cacheFlags are added.

• The REST Config is set to getDefaultRestConfig.

You must not change intents, cache flags nor event manager using the builder.
