[SonarQube] Collect metrics of WORK_DUR

[IanBrison]

What does this PR do?

Add WORK_DUR to the list of the numeric types, to be able to collect additional metrics which are currently skipped.

Motivation

WORK_DUR stands for Working Duration and it represents the estimated effort required to fix issues or achieve certain quality objectives, which basically is an integer value.

Some metrics like the following are skipped because their types are WORK_DUR which is not treated as a numeric type.

• new_technical_debt: Added technical debt
• effort_to_reach_maintainability_rating_a: Effort to Reach Maintainability Rating A
• security_remediation_effort: Security Remediation Effort
• etc.

Some of them are key metrics in SonarQube, and I'd like to have Datadog Agent to collect those too.

Test in my local environment

I've tested the change in my local environment and confirmed that it collects the values without any error.

Hello Datadog team. Thank you for the awesome product!
Sorry for the incomplete PR. I still haven't figured out how to create the CHANGELOG that is required to pass the CI since last time.
If the change is okay, do you mind guiding me or pushing the intended change to this PR?
Thank you in advance.
