Update akka-http version

[i-Alex]

Currently we use version 10.1.9, that has a display error message bug: akka/akka-http#2897
Would be useful for our check on rest api request level to print meaningful error logs in the response body.
We need to upgrade at least to v 10.2.0.
Unfortunately now it requires an update of other akka and jackson dependencies, but akka is taken from Scorex, so would be nice to update it on that level first, otherwise we will have dependency conflicts.
