Elasticsearch 7 introduced Index Lifecycle Management, my aim is to eventually replace curator with this. This update allows for a default ILM policy to be configured for all beats. The default policy is quite basic: an index will be written to for 15 days or until the index reaches 30GB in size, then it will remain in the hot stage (no performance degradation) for another 15 days, after which it will be deleted. This still may lead to a situation where the disk space on log nodes could be filled. ILM policies can be configured for each beat by overriding the defaults that are in the role for each beat. ILM is set up for beats when undergoing an update (elk_package_state="latest"). During ILM set up elasticsearch creates an ILM ready template for the beat and uses the ILM policy we provision to nodes for the initial ILM policy. Subsequent ILM policy updates use ES APIs. New ILM policy files are not provisioned to nodes outside of using the beat upgrade flags, so the policy file on the node may fall out of step. Change-Id: I2c5c3abd4bb65075f2377227cbbfe31b68b0dc38
