[Squad-dev] squad 1.6 release

Hi,

This 1.6 release adds support to queue suffix names, which enables fixing a bug that happens if SQUAD was configured with AWS SQS and a lab entered in maintenance state.

It also adds the ability to switch test results layout when viewing a build home page.

Complete list of changes going in:

* ci: backend: lava: add exception when a lava backend is offline * frontend: * build: add option to change test results layout * views: order environments columns by alphabetical order * settings: * fix notification tasks routing * add support to suffix-named queues

Cheers, Charles
