Possibility for plugins to update settings options value

[kontrollanten]

Describe the problem to be solved

We've a plugin setting that populates its options based on a REST API response:

    try {
      stripePlans = await getStripeSubscriptionPlans(apiKey)
    } catch (err: any) {
      logger.info('Couldn\'t fetch Stripe plans', { err })
    }

    registerSetting({
      name: SETTING_STRIPE_SUBSCRIPTION_PLAN_ID,
      label: 'Stripe plan used for subscription',
      type: 'select',
      options: stripePlans.map((plan) => ({
        value: plan.id,
        label: (plan.product as Stripe.Product)?.name ?? plan.id
      })),
      private: true
    })

Therefore we need to be able to update the available options. When calling registerSettings multiple times it will create a new setting for each call, instead we would like to just update the options.

Describe the solution you would like

Some way of updating the options. Possible solutions:

a) When calling registerSetting with a name that already exists, the new options will override the existing.
b) Add unregisterSetting where you pass the setting name as argument.
c) Add deleteSetting to settingsManager API.
