refactor: normalize log formats across projects

^{Originally posted by **nynymike** February 7, 2022}
Log messages come in different formats; this makes it hard to parse them correctly.

For example, we see logs like:

```
example from scim
07-02 15:17:16.714 INFO gluu.service.logger.LoggerService LoggerService.java:205- Updated log level of '21' loggers to INFO

# example from oxtrust
INFO - webdav - 2022-02-07 15:15:24,402 - Sync files from http://jackrabbit:8080/repository/default/opt/gluu/jetty/identity/custom

# example from oxtrust 2:

# example from oxtrust 3
