[linear]

JAVA-197 MDC tag information not added to logs.

[adinauer]

I would prefer if we also use options.contextTags for log attributes since that way it's consistent with what we do for events. Also starting to send it without opt-in would be something for a major version.

As a first step, I'd just add all MDC values according to options.contextTags.
We could then add support for regex to contextTags and in the next major default contextTags to a regex that simply matches everything.

Yeah that makes sense, changed it.
