IPCClient should be able to connect to running node

[shuse2]

Expected behavior

• Order of initialization should be correct especially schema should be obtained first
• Obtained schema should be exposed
• invoke and event listener is jsonrpc now (add _id, and response handling reject err, and check error prop)
• resolve path const socketDir = path.join(path.resolve(dataPath), ‘tmp’, ‘sockets’);

Actual behavior

• Some name space fail by undefined schema
• It needs another call to get schema
• Response type is outdated
• IPC cannot connect with relative path

Which version(s) does this affect? (Environment, OS, etc...)
