Add "retries" config to teams output module

[domwhewell-sage]

This PR adds a "retries" config option to the teams output module as repeated failures would cause the module to hold up the scan from finishing #2203
Also tweaked the code incase of a 429 response to obtain the Retry-After from the headers as the power automate webhook sends a empty body

Thanks for doing this; it's definitely needed. Since we have a helper with builtin retries, I enhanced it to respect the retry-after header, and made a PR to your PR:

Let me know what you think. The biggest change is that instead of skipping the event, it will disable the module. but only after 100 failed requests (10 requests * 10 total failures). We can tweak the constants if needed. This will help keep the module from getting stuck if there are thousands of events in the queue.
