Update git submodules

* Update docs/submodules/dovetail from branch 'master'
  - Adding a tox environment for locally building docs
    
    Run tox -edocs to locally build the Dovetail docs. This is quite
    useful because the default OPNFV docs preview build toolchain is
    broken for Dovetail.
