### What changes were proposed in this pull request? Restore configuration `metastore.initial.metadata.count.enabled` to prevent metastore metrics startup queries ### Why are the changes needed? For releases as late as Hive 2.3.10, there was support for a `metastore.initial.metadata.count.enabled` configuration property. This could be set to `false` to prevent running queries to determine the counts of existing databases, tables and partitions. In large-scale ephemeral/serverless deployments with many HiveMetaStore processes starting up, this can be a source of unnecessary load spikes on the database. It appears this property was accidentally removed during the Standalone Metastore separation work, specifically in the [HIVE-17307](https://issues.apache.org/jira/browse/HIVE-17307) metrics refactoring. ### Does this PR introduce _any_ user-facing change? Yes, this restores the ability to control configuration for whether or not to run these metrics queries. ### How was this patch tested? Manual testing. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
