Add background upload configuration info to batch deleted telemetry

[maciejburda]

What and why?

Enriches Batch Deleted telemetry metric with backgroundTaskEnabled configuration info.
This is needed for measuring batch delivery success rate based on existence of the configuration.

How?

I have added new field background_tasks_enabled.

in_background is still hardcoded to false, because knowing if the deletion happen in the background is not trivial.
Although I think we're mostly interested in measuring the difference is success rate for two different configurations, rather than knowing if batch file was deleted in background/foreground.

Review checklist

• Feature or bugfix MUST have appropriate tests (unit, integration)
• Make sure each commit and the PR mention the Issue number or JIRA reference
• Add CHANGELOG entry for user facing changes

I like the idea of collecting this attribute 👍. Although we should introduce a new field rather than re-using existing one for different purpose. Otherwise we will invalidate the spec through this PR.
