Add migrate_set_cache_size command
Change XBZRLE cache size in bytes (the size should be a power of 2, it will be rounded down to the nearest power of 2). If XBZRLE cache size is too small there will be many cache miss. New query-migrate-cache-size QMP command and 'info migrate_cache_size' HMP command to query cache value.
