[Documentation] Expand on the documentation of Locking Tables for Writes
The documentation section of https://docs.gitlab.com/ee/development/database/multiple_databases.html#locking-writes-on-the-tables-that-dont-belong-to-the-database-schemas doesn't explain how
- We are doing Monitoring on the locked tables for writes.
- How to manually lock tables if needed. At least until #413656 (closed) is implemented. Using some database migration examples.
- Alerting (when it's implemented) #413654 (closed)
If we do so, we can also let teams take ownership of locking tables for writes on their own database tables. What do you think?
