Switch to logger (#442)

* Switch to logger

Use logger rather than io:format when logging.  The ct tests have besn switched to log to file, testutil/init_per_suite/1 may offer useful guidance on configuring logger with leveled.

As all logs are produced by the leveled_log module, the MFA metadata is uninteresting for log outputs, but can be used for explicit filter controls for leveled logs.

* iolist_to_binary not unicode_binary()

logger filters will be error and be removed if the format line is a binary().  Must be either a charlist() or a unicode_binary() - so iolist_to_binary() can't be used

* Add metadata for filter

* Update test/end_to_end/tictac_SUITE.erl
