Can't disable backward incompatibility for a pattern change #845
Description
When changing the regexp pattern of an existing property, there are no overrides available to explicitly skip the verification on pattern change.
Example:
previous schema
Widget:
type: object
properties:
prop1:
type: string
updated schema
Widget:
type: object
properties:
prop1:
type: string
pattern: '[A-Za-z0-9#$]$'
Gives an Schema: Broken compatibility error.
This issue is to add a new config property (something like incompatible.schema.pattern.changed) so we can disabled the pattern change rule.
