* 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

To allow for extraction of metadata, and building of head responses - it should eb possible to dynamically and user-defined tags, and functions to treat them.
If no function is defined, revert to the behaviour of the ?STD tag.
