fix: add txn retry logic

[Phoenix500526]

Refs: #774
Closes: #774

Please briefly answer these questions:

• what problem are you trying to solve? (or if there's no problem, what's the motivation for this change?)
  FYI: [Bug]: The test case curp::it server::shutdown_rpc_should_shutdown_the_cluster failed #774

• what changes does this pull request make?
  Add a retry logic in write_batch.

• are there any non-obvious implications of these changes? (does it break compatibility with previous versions, etc)
  There is nothing to change breakingly, but we need to do a performance regression test for this modification.
