pytest.ini log_date_format doesn't support %f directive

Hi, ladies and gentlemen!

Some people solve the problem of microseconds in pytest.ini with %(msecs)03d directive in log_format parameter. But there are cases when you need to specify microseconds in log_date_format and %(msecs)03d doesn't support there. For example, I work with logs data with caplog fixture. I get date from LogRecord object like LogRecord.asctime. It returns the format specified in log_date_format, so without %f it seems impossible to get microseconds.

Docs says that log_date_format is strf-compatible, no microseconds there too.

I look at it like at suggestion to include support of %f in log_date_format.

P.S. Sorry if my English might seem bad, I tried my best 😄

based on https://docs.python.org/3/library/logging.html#logging.Formatter.formatTime it seems like this cant be supported nicely in a easy way

we may need a additional config options for the milisecond value

As I understand it, it needs to edit default_msec_format or default_time_format depending on %f parameter contains or not.
