ApplyMetricsData is used for setting the counter values on the WebhookMetrics when stored and accessing for later use.

Metrics returns the defined metrics as a list.

NewFactory creates a Factory from a Viper environment.

NewList just creates an UpdatableList.

Factory is a classic Factory Object for various webhook things.

W is the structure that represents the Webhook listener data we share.

List is a read-only random access interface to a set of W's We don't necessarily need an implementation of just this interface alone.

UpdatableList is mutable list that can be updated en masse.
