Make policy template library's .git directory path configurable
Some aspect of the git configuration for the PolicyTemplate library must be configurable:
- where the .git directory must be ? For now, it is assumed to be in the policies/ directory, what follows usual git convention. But we may want to put it elsewhere, to.
Ex: Vincent has configured its pt lib path in rudder to be /some/directory/policy-templates/policies, where policy-templates/policies is a clone of Normation policy-templates git repository. So, he already has a .git repo in /some/directory/policy-templates/.git, and would have like to use that repos. But the automatic configuration put a new git repos in /some/directory/policy-templates/policies/.git, what is much confusing.
