• Performance: cache regex pattern and result, optimize string concatenation in Envy ALS analyzer.
• Performance: cache metrics id and entity id in Metrics and ISource.
• Performance: enhance persistent session mechanism, about differentiating cache timeout for different dimensionality
  metrics. The timeout of the cache for minute and hour level metrics has been prolonged to ~5 min.
• Performance: Add L1 aggregation flush period, which reduce the CPU load and help young GC.
• Support connectTimeout and socketTimeout settings for ElasticSearch6 and ElasticSearch7 storages.
• Re-implement storage session mechanism, cached metrics are removed only according to their last access timestamp,
  rather than first time. This makes sure hot data never gets removed unexpectedly.
• Support session expired threshold configurable.
• Fix InfluxDB storage-plugin Metrics#multiGet issue.
• Replace zuul proxy with spring cloud gateway 2.x. in webapp module.
• Upgrade etcd cluster coordinator and dynamic configuration to v3.x.

• Performance: compile LAL DSL statically and run with type checked.
• Add pagination to event query protocol.
• Performance: optimize Envoy error logs persistence performance.
• Support envoy cluster manager metrics.
• Performance: remove the synchronous persistence mechanism from batch ElasticSearch DAO. Because the current enhanced
  persistent session mechanism, don't require the data queryable immediately after the insert and update anymore.
• Performance: share flushInterval setting for both metrics and record data, due
  to synchronous persistence mechanism removed. Record flush interval used to be hardcoded as 10s.
• Remove syncBulkActions in ElasticSearch storage option.
• Increase the default bulkActions(env, SW_STORAGE_ES_BULK_ACTIONS) to 5000(from 1000).
• Increase the flush interval of ElasticSearch indices to 15s(from 10s)
• Provide distinct for elements of metadata lists. Due to the more aggressive asynchronous flush, metadata lists have
  more chances including duplicate elements. Don't need this as indicate anymore.
• Reduce the flush period of hour and day level metrics, only run in 4 times of regular persistent period. This means
  default flush period of hour and day level metrics are 25s * 4.
• Performance: optimize IDs read of ElasticSearch storage options(6 and 7). Use the physical index rather than template
  alias name.
• Adjust index refresh period as INT(flushInterval * 2/3), it used to be as same as bulk flush period. At the edge case,
  in low traffic(traffic < bulkActions in the whole period), there is a possible case, 2 period bulks are included in
  one index refresh rebuild operation, which could cause version conflicts. And this case can't be fixed
  through core/persistentPeriod as the bulk fresh is not controlled by the persistent timer anymore.
• The core/maxSyncOperationNum setting(added in 8.5.0) is removed due to metrics persistence is fully asynchronous.
• The core/syncThreads setting(added in 8.5.0) is removed due to metrics persistence is fully asynchronous.
• Optimization: Concurrency mode of execution stage for metrics is removed(added in 8.5.0). Only concurrency of prepare
  stage is meaningful and kept.
• Fix -meters metrics topic isn't created with namespace issue
• Enhance persistent session timeout mechanism. Because the enhanced session could cache the metadata metrics forever,
  new timeout mechanism is designed for avoiding this specific case.
• Fix Kafka transport topics are created duplicated with and without namespace issue
• Fix the persistent session timeout mechanism bug.
• Fix possible version_conflict_engine_exception in bulk execution.
• Fix PrometheusMetricConverter may throw an IllegalArgumentException when convert metrics to SampleFamily
