Update replica version comparison to handle version 8 RC candidates (#851)

Browse Source 
Release candidates have a version that is lower than 8.0.0 to allow for
8.0.0 to have 0x080000 as a release number. However, we did an explicit
check to make sure a version was 8.0 or greater to validate a replica
supports a feature. Now we are using the highest patch version of latest
minor to do the comparison to accommodate future versions.
