rehome remaining common constants
This patch rehomes the remaining neutron.common.constants into neutron-lib. All rehomed constants are put into neutron_lib.constants except for EXT_PARENT_RESOURCE_MAPPING which lives in neutron_lib.services.constants due to circular import refs when rehoming it into neutron_lib.constants or neutron_lib.plugin.constants.
