Custom detekt rule for logger usage check
Check if logger invocations don't use unoptimal invocations, eg. concatenation `debug("a=" + a)` instead of lambda use `debug {"a=" + a}` Unfortunately to avoid defining dependencies in many places and having circural dependencies it was necessarry to reorganize the maven module structure. The goal was to have `sources` module with production code and `build` module with build-time tooling (detekt rules among them). Issue-ID: DCAEGEN2-1002 Change-Id: I36e677b98972aaae6905d722597cbce5e863d201 Signed-off-by: Piotr Jaszczyk <piotr.jaszczyk@nokia.com>
