Elasticsearch Metricbeat module: performance improvements

[ycombinator]

Tracking various memory and performance optimizations we should consider for the Elasticsearch Metricbeat module:

• Reduce memory usage in index metricset: Reduce memory usage of elasticsearch/index metricset #16503
• Consider caching the cluster state API response: [Metricbeat][Elasticsearch] Consider caching the cluster state API response #18997
• Consider using a struct instead of map[string]interface{} to store cluster state: [Metricbeat][Elasticsearch] Consider using a struct instead of map[string]interface{} to store cluster state #18998
• Consider applying index metricset optimizations to the cluster_stats metricset: [Metricbeat][Elasticsearch] Consider applying index metricset optimizations to the cluster_stats metricset #18999
