use bklog.G(ctx) instead of logrus directly

[coryb]

This is a continuation of #2236

I noticed there were several lines in our logs that were missing traceID fields and found they were still using logrus directly.

I have modified a few apis to pass through the context, and in some cases (where a request context was not applicable) I used bklog.L although I could change that to use bklog.G(context.Background()) if that is preferable.

Sorry, looks like this needs a rebase.

As a follow-up would be good to get a linter rule that checks this (unless there are still valid exceptions).

For a linting rule, I think something like jedevc@6377bbb should do the job?

Thanks, I put in something similar, the line anchors ^ and $ I think were preventing matches in my testing, I also added a few more possible matches for logrus to restrict.
