FEAT: support modules - Githubissues

added support for importing TFC modules to env0.

Solution

added http request to fetch all organization's modules
parsed the returned modules and added them to the data.json file
generated new modules file based on data.json content
modules require vcs connection, so added an easier way to provide one (by creating a template via the UI and providing it's name)
generalize the vcs connection so it can be used on environments as well if include_vcs_connection flag is provided
