Help content in assign.rb:
Assign a region. Use with caution. If region already assigned,
this command will do a force reassign. For experts only.
Help content in unassign.rb:
Unassign a region. Unassign will close region in current location and then
reopen it again. Pass 'true' to force the unassignment ('force' will clear
all in-memory state in master before the reassign. If results in
double assignment use hbck -fix to resolve. To be used by experts).
