Upgrade jwt-go version

[ndobosi]

golang/github.com/dgrijalva/jwt-go@3.2.0 package has a known vulnerability issue.

jwt-go before 4.0.0-preview1 allows attackers to bypass intended access restrictions in situations with []string{} for m["aud"] (which is allowed by the specification). Because the type assertion fails, "" is the value of aud. This is a security problem if the JWT token is presented to a service hat lacks its own audience check.
