Description

AWSSecurityTokenService resources can be released whenever they are no longer in use. The documentation of AWSSecurityTokenService#shutdown says while it is not important for client to compulsorily shutdown the token service, client can definitely perform early release whenever client no longer requires token service resources. We achieve this by making STSClient closable, so we can certainly utilize it in all places where it's suitable.
