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).
