* Returns a set of temporary security credentials

* Typically, you use AssumeRole for cross-account access or federation.
*
* @param string $roleArn The Amazon Resource Name (ARN) of the role that the caller is assuming.
* @param string $roleSessionName An identifier for the assumed role session. The session name is included as part of the AssumedRoleUser.
* @param string $policy An IAM policy in JSON format.
* @param integer $durationSeconds The duration, in seconds, of the role session. The value can range from 900 seconds (15 minutes) to 3600 seconds (1 hour).
* @param string $externalId A unique identifier that is used by third parties to assume a role in their customers' accounts.
* @param string $serialNumber The identification number of the MFA device that is associated with the user who is making the AssumeRole call.
* @param string $tokenCode The value provided by the MFA device, if the trust policy of the role being assumed requires MFA.
