The candidate creation logic is further moved into the factory. The
factory would use pkg_resources.get_distribution() to find a matching
distribution for a givan InstallationCandidate. If found, the Candidate
would be created based on that found distribution, instead of the link.
--ignore-installed is implemented as to always use the link to create
candidates, even if an installed distribution is found.
If a dist contains Requires-Python metadata, it is converted into a
Requirement for the resolver based on whether the Requires-Python
is compatible or not.
If it is compatible, an ExplicitRequirement is returned to hold the
Python information (either sys.version_info, or the user-supplied
--python-version).
If it is incompatible, a special NoMatchRequirement is returned, which
never matches to anything, generating a ResolutionImpossible to report
the Python version incompatibility.
The --ignore-requires-python flag is implemented as to not return a
Requirement for Requires-Python at all.
