// Retrieves the specified inline policy document that is embedded with the
// specified IAM role. Policies returned by this operation are URL-encoded
// compliant with RFC 3986 (https://tools.ietf.org/html/rfc3986) . You can use a
// URL decoding method to convert the policy back to plain JSON text. For example,
// if you use Java, you can use the decode method of the java.net.URLDecoder
// utility class in the Java SDK. Other languages and SDKs provide similar
// functionality. An IAM role can also have managed policies attached to it. To
// retrieve a managed policy document that is attached to a role, use GetPolicy to
// determine the policy's default version, then use GetPolicyVersion to retrieve
// the policy document. For more information about policies, see Managed policies
// and inline policies (https://docs.aws.amazon.com/IAM/latest/UserGuide/policies-managed-vs-inline.html)
// in the IAM User Guide. For more information about roles, see IAM roles (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles.html)
