Enhancements to login done by journaler.
Add action to resume pause replicaton.
Merge branch 'release-0.29.x'
Track down and fix the problem with feat gateway failing to offer
the static files.

It turns out it was related to session tracking done by OpenSSL
library. Whether its on or not depends on the version used,
and not to fail it requires a session_id to be set on the context.
Remove leftover log.
Don't collect alerts until the alert agent has loaded the persistent
services.

This potentialy saves a lot of work when receiving the alert triggers
rescanning the shard, which leads to duplicating the definitions
of persistent alerts in database.
When alert agent saves persistent service definition to the database
use coiteration instead of unleashing all the call at once.

This fixes a problem when there is a lot of new services
to save, which could cause other components to fail with
timeouts on startup.
Fix for using update.attributes with list indexes.
Support passing unicode characters as a message to subclasses of
error.FeatError. It does it best to encode it properly.
Fix formatting errors in error handling.
Add missing method in dummy task medium implementation.

Change alert body about unsolvable conflicts to show count instead of
list of ids.
