Epic #85006: Epic: Improve broken link handling in TYPO3 / linkvalidator rewrite
Add configuration option: file with regex patterns to exclude for external link checking
Sometimes there may be problems with external sites that linkvalidator / Guzzle doesn't handle correctly or which can't be handled correctly at all.
To make linkvalidator still usable, it would be good to be able to exclude certain domains / urls using regular expressions. This should be supplied in a way that an admin user can edit it.
Prerequisite: Provide general configuration for extension. This does not need to be made configurable per page tree.
