Extract client code in send_transaction_service into a new structure.

This is the same as PR#3423 but with minimized API changes in STS. In order to be able to use new client code in the `SendTransactionService`, I need to wrap network-related code with the new structure ConnectionCacheClient. To to that I also had to move some auxiliary code into separate files.
