* Fix IAM instance profiles assignments for proxy and nodes
* Add support for auth server certificate verification done by
nodes and proxies joining the cluster.
* Fix out of order events returned by auth servers in HA mode.
In HA mode, auth server could return events out of order
in case if they were sent to multiple auth servers what confused
the user interface expecting events sorted.
This commit fixes the problem by sorting events returned
by function SearchEvents.
