BUGFIX: Graylog cannot parse log_timestamp

[YuryHrytsuk]

Problem

This PR fixes the bug described in #426. In short, simcore services logs and traefik logs contain timestamp of different format which leads to occasional failure to parse any simcore service logs.

Solution

By stopping capturing timestamps generated by traefik, we make sure that all log_timestamp values have the same format

For history and future usage

There are multiple solutions to this problem. We can create custom index mapping and tell explicitly ES which type should have log_timestamp but there is no easy solution to access ES API since ES is not reachable from the outside.

Other solution is to introduce T separator in all log_timestamps generated by simcore services (currently space is used as a separator which ES date type do no understand by default).
