[metrics] Add table level metrics column_count and schema_version on master
This patch adds some table level metrics on master.
- column_count: The column count in the table's latest schema. Since too
many column count will lead to bad performance and space
amplification, we can add some monitor alerts based on this
metric after this.
- schema_version: The table's schema version. Too many or too
frequently schema changes is also a metric worth to be monitored.
