Varnish Controller 5.2.1 Release

This is a patch release for Varnish Controller with the following fixes:

• All components built with Go 1.20.5
• Bug fix where organization user with only read access to agents/routers could assign/remove tags. Now write access to agent/routers is required to assign/remove tags.

• Improved performance when using API filters.
• Router health probes and invalidations now supports IPv6.
• Updated default VCL templates:
  • Default Root VCL file (shared deployments) now responds 404 Not Found for requests towards a domain that is not deployed on the Varnish server.
  • Default temporary VCL that is used when nothing is deployed, now responds 404 Not Found to all requests.
  • These VCL templates can be customized, see Agent - Default VCL and Agent - Default Root VCL
• UI: Fixed a table bug when there was multiple pages and deleting a resource would redirect to first page.
• UI: Improvements to table column filter.
• UI: Fixed a bug when filtering on Varnish State Unknown wouldn’t work.
