Why Does AuraDB Only Have a Subset of APOC calls?

Aura has historically been cautious of procedures that can interact with the filesystem or that can make internet requests. Very few of them are enabled. 

For example, if you run apoc.import.csv you'll get an error like the one below:

Failed to invoke procedure `apoc.import.csv`: Caused by: java.lang.RuntimeException: Import from files not enabled, please set apoc.import.file.enabled=true in your apoc.conf

You'll see please set apoc.import.file.enabled=true. Because there's no way to write the apoc.config there's no means to import from the file system using APOC. Note that the same applies to apoc.export.* as well. It also requires setting a flag in the apoc.conf file to enable.
