Flag a group as "no changes dispersed"

As part of running Grouper, Groups get constructed and distributed to LDAP and other applications. The names of groups and their content becomes critical to the proper operation of applications. Sometimes, as experience grows, the way groups are formed change and need to be re-implemented. Most notably, a composite group wasn't constructed to be sufficiently flexible (or wasn't initially a composite) and the group needs to be re-constructed. During this time of reconstructing the group, no changes should be dispersed via any changelogs so the applications depending on the groups operate un-injured by changes. I'd like to flag a group as "no changes to be dispersed" and then I can fix the group without penalty. When I remove the flag, operation returns to normal. Any mechanisms for resyncing the group may be needed to make sure changes weren't lost, depending on how the consuming application uses the group in question. The sync'ing of a group is outside the scope of this enhancement request.
