Title: Reduce execution time of repl test (v2 and v3)

The most time consuming part is five retries for getting blocks.
After making retry number configurable, use small number `1` for testing.

There are also some misc refinement such as removing sleep or replacing sleep with `wait_until`.

One example of execution times are as follows.

Before
- repl_test 20.78s user 8.88s system 7% cpu 6:26.88 total
- repl_v3_test 21.25s user 9.68s system 6% cpu 7:44.34 total

After
- repl_test 21.09s user 10.34s system 41% cpu 1:15.17 total
- repl_v3_test 20.61s user 9.04s system 23% cpu 2:04.00 total
