    Some clients like Apache Phoenix do not use the guice modules. They 
instantiate `TransactionServiceClient` directly. It will be good to have the 
existing constructor too and assign the default value for the clientId in it.


> Introduce client ID that can be used to track requests per client

> Today transaction manager does not have details of what transaction belongs 
> to which client. For instance when a there are a lot of invalid transactions 
> generated by a client, it is not easy to say which client generated the 
> invalid transactions. Transaction manager just logs a message saying the 
> transaction ID was invalidated. This makes debugging very difficult since 
> there is no easy way to map the transaction ID to a program.
> Transaction APIs should allow clients to pass in client IDs for every start 
> transaction call. Transaction manager can store this client ID as part of the 
> transaction metadata. And when transaction manager logs messages with 
> transaction ID, it can include the client ID in the message.
