Improve gateway client connection timeout #2480

#2475 introduced a new mechanism for adding IO client specific logic for determining if the connection is established

Gateway clients use this to add asset sync to connection so if a failure occurs in this phase the retry logic still applies but the problem with this is that the Gateway now sets a 60s timeout on the connection/init but if the gateway cannot even establish a connection to the server the 60s timeout is still used whereas the connection should fail earlier in this scenario.
