SSH client has a max number of open channels for a connection, if we set the number of trialCurrency too big, our ssh client will exec command using ssh frequently, then we will meet the error of Error: (SSH) Channel open failure: open failed.
Refactor the code, set one connection has a max trial concurrency, when the number of trial reach the ssh connection restriction, will create a new ssh connection to exec trial commands.
