Audit trail configuration

Configuration of the audit trail, of the storage of its evidence, and of the demonstration tampering switch.

Name	Environment	Description	Default value
`ontrack.extension.audit-trail.demo-tampering.enabled`	`ONTRACK_EXTENSION_AUDIT_TRAIL_DEMO_TAMPERING_ENABLED`	Allows a global administrator to rewrite the payload of a trail entry through the API, to demonstrate a broken chain. Never enable it in production: while it is on, the trails of the instance prove nothing, and every page says so in a permanent error message.	false
`ontrack.extension.audit-trail.storage.access-key`	`ONTRACK_EXTENSION_AUDIT_TRAIL_STORAGE_ACCESS_KEY`	Access key of the S3-compatible service. Required.
`ontrack.extension.audit-trail.storage.bucket`	`ONTRACK_EXTENSION_AUDIT_TRAIL_STORAGE_BUCKET`	Name of the bucket storing the evidence. It must exist. Required.
`ontrack.extension.audit-trail.storage.endpoint`	`ONTRACK_EXTENSION_AUDIT_TRAIL_STORAGE_ENDPOINT`	URL of the S3-compatible service storing the evidence, for example `https://fra1.digitaloceanspaces.com` or `http://minio:9000`. Required.
`ontrack.extension.audit-trail.storage.max-size`	`ONTRACK_EXTENSION_AUDIT_TRAIL_STORAGE_MAX_SIZE`	Maximum size of one evidence, for the whole instance. In megabytes when no unit is given.	50 (MEGABYTES)
`ontrack.extension.audit-trail.storage.path-style`	`ONTRACK_EXTENSION_AUDIT_TRAIL_STORAGE_PATH_STYLE`	Path-style addressing (`<endpoint>/<bucket>`), as MinIO needs, instead of the virtual-hosted one (`<bucket>.<endpoint>`), as AWS S3 and DigitalOcean Spaces use.	false
`ontrack.extension.audit-trail.storage.region`	`ONTRACK_EXTENSION_AUDIT_TRAIL_STORAGE_REGION`	Region of the bucket. MinIO accepts any region; DigitalOcean Spaces wants the region of the endpoint, for example `fra1`.	us-east-1
`ontrack.extension.audit-trail.storage.secret-key`	`ONTRACK_EXTENSION_AUDIT_TRAIL_STORAGE_SECRET_KEY`	Secret key of the S3-compatible service. Required.
