EX-6298 lipe: decrease delay before ALR restart

- Decrease delay before restarting access log reader and
eliminate this delay when the read from ALR fails
due to timeout. Increase SSH poll/read timeout while
keep-alive message in ofd_access_log_reader is not
implemented
This will decrease probability of missing ALR.
- Remove excluding hot-pools test_72
