# This script does the following:
# 1.) Lock all MySQL tables and flush data to disk.
# 2.) Call Zerto REST API and insert a User defined Checkpoint
# 3.) Unlock the MySQL tables and resume normal operations
#
# You must provide the VPGID for the VPG that needs the checkpoint inserted.
# To get this information
