[logger] Change default primary log level to 'notice'

Log events issued via error_logger:info_msg or
error_logger:info_report are now forwarded to Logger with level
'notice' instead of 'info'.

Log events issued by gen_* behaviours are also changed from level
'info' to level 'notice'.

Progress reports are still 'info', and can therefore easily be
included/excluded by changing the primary log level. By default, they
are not logged.
