Summary: Pip module would abort when name is a remote package address because the module was expecting a version if ``=`` is part of the name value. Furthermore, the pip module would require either name or requirement to be a key, although the documentation table said neither was required. The fact that one of them must be present is not documented in the documentation leads to confusion. This commit added this fact as part of description. In this commit, we resolve the confusion by stating either ``name`` or ``requirement`` is needed. Next, if the user puts remote address as the value of the ``name`` key, we will not use mirror. Lastly, if the user uses the remote serivice address as the name of the package and the user does not supply -e option in extra_vars (which is the whole point of this commit), we will add -e to extra_vars so pip command can run with -e option.
