/**
* Represents a security configuration to be used for servers. There is no generic mechanism for
* processing arbitrary {@code ServerCredentials}; the consumer of the credential (the server)
* must support each implementation explicitly and separately. Consumers are not required to support
* all types or even all possible configurations for types that are partially supported, but they
* must at least fully support {@link ChoiceServerCredentials}.
*
* A {@code ServerCredential} provides server identity. They can also influence types of
* encryption used and similar security configuration.
*
*
The concrete credential type should not be relevant to most users of the API and may be an
* implementation decision. Users should generally use the {@code ServerCredentials} type for
* variables instead of the concrete type. Freshly-constructed credentials should be returned as
* {@code ServerCredentials} instead of a concrete type to encourage this pattern. Concrete types
* would only be used after {@code instanceof} checks (which must consider
* {@code ChoiceServerCredentials}!).
