Introduce OWNCLOUD_CONFIG_DIR environment variable

[bachp]

Description

The environment variable OWNCLOUD_CONFIG_DIR allows to move the config out of the source tree. This is usefull to make the rest read-only.

Motivation and Context

Allow to have the source directory read-only.
Nextcloud has a similar variable called NEXTCLOUD_CONFIG_DIR so there it is already working.

How Has This Been Tested?

Running an Owncloud server 9.1.5 with a read only source directory.

Looks fine.

@DeepDiver1975 @butonic thoughts ?

[PVince81]

Will need clear documentation because the config dir needs to be writable by the web server process, wherever it is. So all parent folders leading to it needs to be traversable by the web server process too.

I'd be tempted to say "not officially supported, use at your own risk"

[bachp]

I think this will be mostly used in special cases. For example NixOS uses it as the main code directory is read-only.

@PVince81 - this was never introduced in ownCloud 10 :'(

@tboerger
this would get rid for the need of having a symlink in the docker containers
