Add -c option for partitioning commands

Adding 'continue' option to:
gp create
enh_area set
write_reliability set

Partitioning commands are connected, register PARTITION_SETTING_COMPLETED
should not be written until all settings have been done.
The continue option enables writing more than one partitioning setting before
sealing settings.
