security: Native key provider is incompatible with some secret providers

[dnephin]

Describe the bug

The native key provider (currently called NativeSecretProvider) accepts a secretProvider , but is partially incompatible with the env provider and incompatible with the plaintext provider because those secret providers either do not support SetSecret, or setting a secret is not meaningful (ex: setting an env var for the process).

Related to #1632

Expected behavior

When the native key provider is configured with either an env provider or plaintext provider, Infra should error before starting the server.
