Fixes #2355

This works around an issue with cleo's `Command.choice` implementation.
If the user does not make a selection then an AttributeError is raised.

This change ensures that the provider is less eager when merging
duplicate dependencies for a package. In particular, takes into
consideration source type, url and reference if available.

Use the version from poetry.core always, one implementation is enough

Testing against newer versions will help us keep abreast of any upcoming
issues. The older versions can be added as partial matrix entries if
desirable, but I do not believe this to be necessary.

Also re-order mypy in the workflow so that type errors fail fast (before
tests are run).

perf(solver): reduce the number of overrides by avoiding adding dummy dependencies if the project's python constraint does not allow any version compatible with the marker of the dependency

Co-authored-by: Bjorn Neergaard <bjorn@neersighted.com>

This change ensures that when http repositories inspect package
metadata from py2 and py3 wheels, python version requirements are
merged. Without this change, in cases where these wheels have different
python constraints, attempting to lock these packages will lead to
solver errors.

Resolves: #5074

This change replaces the `--no-binary` option introduced in #5600 as
the original implementation could cause inconsistent results when the
add, update or lock commands were used.

This implementation makes use of a new configuration
`installer.no-binary` to allow for user specification of sdist
preference for select packages.
