Consider adding autostart property to SqsOptions.Listener

Type: Feature

Is your feature request related to a problem? Please describe.
There are cases in which we might wanna have SQS integration (e.g. publishing messages) but disable SQS listeners. But currently there's no easy way to do this via configuration properties.

Describe the solution you'd like
Add a boolean flag to SqsProperties.Listener class; autostart or autoStartup (if you wanna be consistent with the property in SqsContainerOptions class).

Describe alternatives you've considered
Disabling the whole SQS integration (using spring.cloud.aws.sqs.enabled) but it doesn't support this exact use case.

Additional context

Happy to send the PR if needed.

Hi @akefirad, sounds good, looking forward to the PR.

I may be missing something, but couldn't you mark listener beans as @ConditionalOnProperty("listeners.enabled") and just not create these beans at all when they are not needed?

[akefirad]

Sure, that could work. But it's not as flexible as the boolean auto-start flag. Also seems a bit cleaner to me. No strong opinion. LMK.
