Feature request - set logging level in BluetoothConfiguration.

[medvednic]

Currently there are explicit calls to Log.v in BluetoothLeService. It would be vary helpful to set logging level in BluetoothConfiguration, something like:

    config.logLevel = "debug";

I can look at this in the future, I'm very busy at the moment.
