Support Event Trigger Retry Logic

### Component

Event Triggers

### Is your proposal related to a problem?

Currently, the configuration for retries allows for setting a fixed number of retries and a specified delay between them. However, it lacks support for exponential backoff, which could be crucial in scenarios where a webhook might encounter issues or latency.

### Describe the solution you'd like

Requesting support for a multiplier or backoff algorithm to allow the configuration of a threshold that would be respected before initiating retries. This approach would prevent exhausting all retry attempts within a short time frame and enhance the likelihood of successfully processing the event.

Start by locating the Event Triggers retry configuration and its existing fixed retry and delay behavior. No file or test is named; clarify the multiplier or backoff configuration, its retry semantics, and the tests needed to verify delayed retries before implementation.
