Updating docs and adding task manager monitoring config. Adds support and docs for: * xpack.task_manager.monitored_stats_health_verbose_log.enabled Kibana Task Manager configuration * xpack.task_manager.monitored_stats_health_verbose_log.warn_delayed_task_start_in_seconds Kibana Task Manager configuration

Updating docs and adding task manager ephemeral tasks config. Adds support and docs for: * xpack.task_manager.ephemeral_tasks.enabled Kibana Task Manager configuration * xpack.task_manager.ephemeral_tasks.request_capacity Kibana Task Manager configuration * xpack.alerting.maxEphemeralActionsPerAlert Kibana Alerting configuration

Add stricter validation to create/update deployment templates. When creating or updating a Deployment template, if it specifies node_roles in the Elasticsearch plan, the template must contain all resource types and all Elasticsearch tiers.

Add docs about supporting node_roles and autoscaling. Adds docs on how to update ECE custom templates, to support node_roles and autoscaling.
