Allow updating JWT authentication client assertions

[ArikWiz]

Describe the feature request?

When using JWT authentication, the client assertions in the configuration are static, and won't be updated after the token expires in

func (a *JWTAuth) Authorize ... {
   ....
   accessToken, nonce, privateKey, err := getAccessTokenForPrivateKey(a.httpClient, a.orgURL, a.clientAssertion ...)
   ....
}

compare that to:

func (a *PrivateKeyAuth) Authorize {
   ...
   clientAssertion, err := createClientAssertion(a.orgURL, a.clientId, a.privateKeySigner)
   ...
}

i think allowing for the ClientAssertion to be a callback rather than a string, in JWTAuthConfig, would solve the issue
