---

This PR adds a log which will be emitted at a configurable interval (default of 1 minute), in the event of there being a locked user anywhere in Vault. This adds visibility for operators around the user lockout feature via the operational logs, allowing them to know when a user lockout is in effect. A WARN log will be emitted when a lockout is in effect, and an INFO log will be emitted when all lockouts have been cleared. The log interval can be modified as part of the server config using the user_lockout_log_interval parameter.

Example Config:
user_lockout_log_interval="30s"
