Watcher: Allow configuring custom email service. Custom Watcher email accounts can now be configured.

Configurable batch size of the Endpoint user artifact packager. The xpack.fleet.createArtifactsBulkBatchSize configuration option enables you to adjust the batch size used when creating or editing Endpoint user artifacts such as Trusted Applications, Event Filters, or Endpoint Exceptions. This is useful for users that maintain large amounts of Agent Policies with the Elastic Defend integration enabled. It should only be necessary to adjust when you notice strain on your systems when editing or creating Endpoint user artifacts.
