Update git submodules

* Update upstream/vswitchperf from branch 'stable/colorado'
  - docs: Update links for Colorado 2.0
    
    References among VSPERF documents are realized by html links
    to the final doc version stored inside the artifactory.
    These links are release specific and have to be updated
    for every new release or release version. This patch
    prepares links for Colorado 2.0 release.
