Move install operations to partitions field in major version 2.
install_operations and kernel_install_operations will be empty in major
version 2, they are now present in partitions field.
partition_info are still in old location, more refactoring are needed before
moving them.
This patch also moves the kLegancyPartitionName constants from install_plan.h
to payload_constants.h.
TEST=cros_generate_update_payload generate same payload version 1 as before.
Call delta_generator manually with --major_version=2, then cros payload show.
cros_workon_make update_engine --test
