Deprecate custom LazyLogging

[metasim]

geotrellis.util.LazyLogging was originally necessary mark the logger as @transient, to ensure that the logger didn't get serialized as a part of a Spark RDD closure. Modern versions of com.typesafe.scalalogging.LazyLogging properly use the @transient annotation. Library users should be encouraged to use the official LazyLogging over the GeoTrellis one.

The migration path (across major GT release) should be:

1. Mark the trait as @deprecated and update all of GeoTrellis to use the standard version
2. Remove geotrellis.util.LazyLogging from GeoTrellis.

@metasim oops we've removed it already (: I don't think that it was so popular that everybody used it.

Cool. I keep accidentally using it, but I'm on 2.1.0.

[pomadchin]

If you're on 2.1.0 you should use it. In the 2.1.0 typesafe LazyLogging doesn't have a transient logger, that's why we had our own version of the same thing.

I meant I was on Geotrellis 2.1.0. I'm on ScalaLogging 3.9.0, which properly handles @transient.
