Allow for a configurable config.yml location.

[ltomes]

On many devices like an Nvidia shield /data/* is a privileged directory.

It would be helpful to include a configuration in the app so an alternative location can be set for use on a device where root is not available.

In a use case like this do you have any ideas I should try? I'm not above baking my config.yml into the apk at build time if that gets me a working prometheus exporter for an Nvidia Shield!

Hello,
the documented path might be different for other platforms I did not consider at implementation time. The configuration file is taken from directory returned by this call: https://developer.android.com/reference/android/content/Context#getFilesDir().

I would suggest looking at return value of context.filesDir for your specific platform.
