This commit adds two APIs that allow to pause and resume CCR auto-follower patterns: // pause auto-follower POST /_ccr/auto_follow/my_pattern/pause // resume auto-follower POST /_ccr/auto_follow/my_pattern/resume The ability to pause and resume auto-follow patterns can be useful in some situations, including the rolling upgrades of cluster using a bi-directional cross-cluster replication scheme (see elastic#46665). This committ adds a new active flag to the AutoFollowPattern and adapts the AutoCoordinator and AutoFollower classes so that it stops to fetch remote's cluster state when all auto-follow patterns associate to the remote cluster are paused. When an auto-follower is paused, remote indices that match the pattern are just ignored: they are not added to the pattern's followed indices uids list that is maintained in the local cluster state. This way, when the auto-follow pattern is resumed the indices created in the remote cluster in the meantime will be picked up again and added as new following indices. Indices created and then deleted in the remote cluster will be ignored as they won't be seen at all by the auto-follower pattern at resume time. Backport of elastic#47510 for 7.x
