Feature request type

Are there any plans to implement JSON parsing support in order to support server software that emit structured logs?

Description

I was trying to write some configuration files so that Fail2ban would work with the Caddy webserver (which emits JSON access logs), but realized matching stuff within JSON using regex might be a bad idea. Off the top of my head the JSON structure might change around causing the filter to break, or match incorrect host addresses, etc.

Considered alternatives

Use something like jq to pre-process and extract needed data (possibly issue #2992?)

Any additional information

Issues (for specific server software):

• MongoDB - MongoDB 4.4 logs are in .json format and not recognized  #2932
• Nginx (custom log format) - Custom NGINX Log Format #3456
• PPTP VPN - Support for banning failed authentication into PPtP VPN servers #2754
• Gitlab - [FR]: GitLab, application_json.log, application.log (deprecated) #3566

I haven't found a general issue/RFE for JSON parsing via searching, but please let me know if there is one and this is a duplicate and I will close it.
