Add logging for executing queries (#134)
* Add logging for executing queries

Arguments are translated to Log::Metadata::Value via DB::Statement#arg_to_log method.

DB::Statement#before_query_or_exec & after_query_or_exec protected methods can be used to hook and run around the statement execution

* Move the metadata converter to a module

* Replace before/after with def_around_query_or_exec macro

* Update src/db/enumerable_concat.cr
