Please update version number of submodules

[ZhuJiaqi9905]

It seems that the version of some submodules (e.g. caladan, parses) is behind the lastest version. I read the git log of caladan and found that there are some "bug fix" after caladan@4a254bf. Besides, the dpdk version in caladan is invalid.
I think that caladan is a novel and systematic project, and I am not sure which version should I choose to successfully run caladan and those apps.
Would you please check and update those version numbers of submodules? Thanks a lot.
