Parts of dcorch.common.consts: such as ENDPOINT_TYPE_*, ENDPOINT_TYPES_LIST, SYNC_STATUS_*, and so on, are shared by dcmanager, so they should be moved into the dccommon.consts. Test Plan: PASSED: All distributedcloud sanity tests. Closes-Bug: 1978334 Change-Id: I13d7ec72e2863171138b39cd8f982d69e87d60b8
