[Feature] Provider - allow enabling/disabling self-service, changing name

[jcace]

Update the Providers ui to allow the user to enable or disable the self-service for that provider, as well as changing the friendly name.

This will be controlled by a boolean flag allow_self_service on the provider - true = enabled, false = disabled.

If self service is disabled, the provider's API key/UUID could be hidden as it's not relevant unless enabled.

API request to update it :

POST /api/v1/providers/f012345

body:

{
        "actor_name": "jason",
        "allow_self_service": true
}
