[8.x] Fifo support for queue name suffix

[ArronKing]

PR to add support for fifo naming conventions.

A FIFO SQS queue must always end with .fifo. For example, you set a queue name of emails.fifo and a suffix of -staging you end up with a queue name of emails.fifo-staging. After this PR you get emails-staging.fifo.

I appriciate FIFO queues aren't supported by the Framework. But there are packages that add support. This PR just adds support for the naming convention.

Thanks

I don't think just jamming fifo on a queue is enough. Laravel doesn't understand group ids.

Yeah I agree, but I'm not trying to add FIFO support. This focused on fixing(?) the naming of fifo queues when using a suffix.

Using a suffix of -production and a FIFO SQS queue with the name emails.fifo. We should end up with the name emails-production.fifo not emails.fifo-production?

If it helps, my use case is I'm using https://github.com/shiftonelabs/laravel-sqs-fifo-queue to add Fifo support. But would still like to use some Laravel queue features, like artisan queue:work and artisan queue:monitor etc. These don't really care if it's a standard queue or fifo queue, but in order for them to work we need the suffix to be in the correct place.

Thanks again
