[Feature] Add a local provider to send sms alert notification

### Feature Request

I use a local provider to send sms alert notifications, and I would like to add it to the existing supported providers

### Is your feature request related to a problem? Please describe

No

### Describe the solution you'd like

I want to have the option to configure my local provider the same way as the existing providers to send sms alert notifications.

### Describe alternatives you've considered

Tried a webhook, did not work

### Additional context

-

No files, tests, or entry points are named. Start by reviewing the existing supported SMS providers and their configuration flow, then identify how a local provider can follow the same pattern; done means the provider can be configured and used to send SMS alert notifications.
