Feature request: being able to override the cache- and logs-directories

[tvdijen]

I would like to be able to override the logs- and cache-directories.
For all the other stepup-apps, I can edit the src/AppKernel.php file to do this, but the azuremfa-module doesn't have this file. This means I have to edit vendor/symfony/http-kernel/Kernel.php which is kinda horrible.

This feature request is two-legged:

1. Be able to override the directories in the azuremfa-module without touching the vendor-dir
2. Ideally, make it possible to do this by configuration instead of editing PHP-files (this applies to all stepup-apps)

2. would also apply to EngineBlock
