Support non-git repositories

I’d like to be able to use conan-package-tools using perforce and jenkins (and storing packages in artifactory), in the current release (correct me if I’m wrong) this is not possible because ci_manager tries to call git log:

fatal: Not a git repository (or any of the parent directories): .git
Traceback (most recent call last):
  File "build.py", line 4, in <module>
    builder = ConanMultiPackager(visual_versions=["15"], gcc_versions=["6"], clang_versions=["9.0"], archs=["x86_64"])
  File "/Library/Python/2.7/site-packages/conan/packager.py", line 106, in __init__
    self.ci_manager.get_commit_build_policy() or \
  File "/Library/Python/2.7/site-packages/conan/ci_manager.py", line 54, in get_commit_build_policy
    matches = prog.match(msg)

@memsharded Yes that was the case, I had 2 different versions of conan, 0.30.0 on ~/Library/Python/ and 1.2.1 on /Library/Python.

Importing conan version using: from conans import __version__ as client_version reported 0.30.0, but conan in my path was v1.2.1

I uninstalled 0.30.0 and now everything works fine! Thank you @lasote and @memsharded for all your help 🥇

Yes, you always need to specify the “.”: conan create <path> <pkg-reference> => conan create . user/channel, from conan 1.0. Is it possible that you had an older conan version (<1.0) installed?
