Add graalvm reachability metadata to sso service

[gbaso]

Describe the feature

Add reachability metadata for service sso, namely for the constructor of SsoProfileCredentialsProviderFactory.

Use Case

GraalVM native image requires reflection hints for code that is only used by reflection.

Proposed Solution

Add a file reflect-config.json under src/main/resources/META-INF/native-image/software.amazon.awssdk/sso with:

[
  {
    "name": "software.amazon.awssdk.services.sso.auth.SsoProfileCredentialsProviderFactory",
    "methods": [
      {
        "name": "<init>",
        "parameterTypes": []
      }
    ]
  }
]

Other Information

Native hints can be provided by the application (e.g., for spring applications, via @ImportRuntimeHints), but it's mostly a try-and-error process. Libraries providing metadata simplify the operation of building a native image considerably.

Other aws services already provide metadata, see ssooidc.
