qmp: add interface blockdev-snapshot-delete-internal-sync
This interface use id and name as optional parameters, to handle the case that one image contain multiple snapshots with same name which may be '', but with different id. Adding parameter id is for historical compatiability reason, and that case is not possible in qemu's new interface for internal snapshot at block device level, but still possible in qemu-img.

+blockdev-snapshot-delete-internal-sync
+--------------------------------------
+
+Synchronously delete an internal snapshot of a block device when the format of
+image used supports it. The snapshot is identified by name or id or both. One
+of name or id is required. If the snapshot is not found, the operation will
+fail.
+
+Arguments:
+
+- "device": device name (json-string)
+- "id": ID of the snapshot (json-string, optional)
+- "name": name of the snapshot (json-string, optional)
