Fix broken replication_log, include task-id in every log

Utilize Flogger's logging tag feature. A small disadvantage is that
the trace context is a part of the log message i.e. we cannot really
control the layout. What was earlier:

[2020-05-04 ...] [c0b3774c] Missing repository could not be created when replicating <repo-url>

becomes now:

[2020-05-04 ...] Missing repository could not be created when replicating <repo-url> [CONTEXT PLUGIN="replication" pushOneId="c0b3774c" ]
