Introduce a new configuration that skip storing audit payload if payload
size exceed configured limit
### Description
Audit log such as coordinator.compaction.config can get very large as
datasources and their configurations churn. This can cause problems such as
- Metadata database taking up too much space / running out of storage space
- Configuration change (such as compaction configuration) failing as we are
not able to insert new row into audit table due to exceeding the database size
limit (max_allowed_packet, etc)
This PR introduce a new configuration that skip storing audit payload if
payload size exceed configured limit. The default value is set to -1 which
disables this check, meaning Druid will always store audit payload regardless
of it's size.
