Update git submodules

* Update docs/submodules/oom/offline-installer.git from branch 'master'
  to e7fd64586455a7c1270c1b1c846c19e030780315
  - Merge "Don't set 'container' env in Molecule containers"
  - Don't set 'container' env in Molecule containers

    Molecule role tests that use pre build images had
    superfluous 'container' env variable declaration.
    It's not needed as this env is already set in
    Dockerfiles, for both: pre-built and custom built
    images.
