Return a QDict, which may contain more two QDicts, depending on
the type of migration we're performing.
IMPORTANT: as a QInt stores a int64_t integer, RAM values are going
to be stored as int64_t and not as uint64_t as they are today. If
this is a problem QInt will have to be changed.
This commit should not change user output.

+ * do_info_migrate(): Migration status

+ * Return a QDict. If migration is active there will be another

+ * another one with block migration status.

+ * The main QDict contains the following:

+ * - "status": migration status
+ * - "ram": only present if "status" is "active", it is a QDict with the
+ * following RAM information (in bytes):
