Subject: [PATCH 1/3] MEDIUM: log: add options eval for log-forward

This commit adds parsing of options in log-forward config sections and
prepares the scenario to implement actual changes of behaviuor. So far
we only take in account proxy->options2, which is the bit container with
more available positions.
