Add support for index pattern exclusion in CCR AutoFollow (#72935)

Browse source 
This commit adds the ability to specify exclusion patterns in Auto-Follow patterns. This allows excluding indices that match any of the inclusion patterns and also match some of the exclusion patterns giving more fine grained control in scenarios where this is important.
