Option to not require a valid api key for provider initialization

[pyranja]

Hi,

we are using the statsig provider in an internal re-usable module. If a service requires feature flags, the statsig support can be toggled on in the module. Due to the way terraform works, the module now always requires the statsig provider declaration (even if it's not actually used).

As of now, declaring the provider also requires a valid api key, which is checked when the provider is initialized.
While such a validation is useful to fail fast, in our case it complicates the situation.

For example the datadog provider offers an option to disable api key validation (https://registry.terraform.io/providers/DataDog/datadog/latest/docs), can you add such an option too?

@pyranja I think the use case makes sense. We will update the provider to allow initializing without an API key. However, our validation is quite lax at the moment. I think you can just set the api_key to be any non-empty string (e.g. "123") and it'll pass the validation. In case you are looking for a workaround.
