rCOMM43cc1b683217: [services] Tunnelbroker - Switching to use composite key in a messages table in…

Summary

To avoid possible message UUID collision and speedup batch messages deletion we should switch to using the composite key for the tunnelbroker-messages table which will consist of messagesID as a Sort Key and toDeviceID as a Partition key.

This diff is a part of the stack and introduces changes for Terraform.

Linear task: ENG-1362

Test Plan

These changes should be tested at the D4475 diff. The current messageItem related tests at services/tunnelbroker/test/DatabaseManagerTest.cpp should not fail including:

PutAndFoundMessageItemsStaticDataIsSame
PutAndFoundMessageItemsGeneratedDataIsSame
PutAndFoundByReceiverMessageItemsDataIsSame

Shouldn't we also modify the entity files? I'd put the fields in this file (especially in the constructor) in the correct order which would be:

partition key
sort key
the rest of the fields

So, for the messages this would be:

toDeviceID
messageID
fromDeviceID
payload
...

What do you think? Sorry for requesting changes but I wanted to push it to your queue.
