Issue 51102 - RFE - ds-replcheck - make online timeout configurable
Bug Description: When doing an online check with replicas that are very
far apart the connection can time out as the hardcoded
timeout is 5 seconds.
Fix Description: Change the default timeout to never timeout, and add an
CLI option to specify a specific timeout.
Also caught all the possible LDAP exceptions so we can
cleanly "fail". Fixed some python syntax issues, and
improved the entry inconsistency report
