We automatically disable heavy mysqld_exporters since
PMM-4937. Now we need to make it configurable.
Things to do:
- Configure a number of tables per Agent, with 1000 as a default value.
- Provide a CLI flag to change that value.
- Show current status of tablestats collectors in CLI after pmm-admin add.
Things that we discussed, but are not in scope:
- Update Parameters of Service (another issue).
- Restart Agent once per day to re-check a number of tables.
