Config Property for Turning on Config Cache

Any reason why there is not a config property we can set in .env to turn on the new Config cache feature? I don't like modifying the index.php file.

Simpler is always better

this is a test feature. not for everyone. you can add the code for Config, env yourself or send PR on github

1. because the prerequisites are complex and the feature is not suitable for everyone.
2. to reduce the overhead to zero when Config Caching is not used.
