Inconsistent sorting of result set of messages when sort is not given

[Coduz]

Describe the bug
Invoking

• GET messages
• POST messages/_query (with no sort order defined)

via REST API will result in a not ordered result set which makes paginating not working.
This is likely due to the fact that a default sort is not defined.

Expected behavior
There should be a default ordering when requesting data.

• Messages sorted by timestamp DESC
• ChannelInfo sorted by full channel name ASC
• ClientInfo sorted by full client id ASC
• MetricInfo sorted by full channel name ASC

Screenshots
None

Version of Kapua
