Make WaitForReady functionality optional with the new default being fail-fast #66
Description
To bring the JS client in alignment with other language clients for Coherence, fail-fast will be the default operating mode. Fail-fast meaning if connection is down, RPCs will fail immediatly. Wait-for-ready will wait for the connection to become ready blocking the RPC.
The ready timeout we currently have will control this. If the config value is zero (the new default), operating mode is fail-fast. If a positive numeric value, then wait-for-ready will be used.
