This reverts commit 65ba952f.

* Add custom certificate authority and client certificate support

* Add documentation on certificates

* Add cli options to publish for cert and custom ca

* Fix requests+pathlib problem and logic hole when BasicAuth+certs are used

* Rename custom-ca to cert

* Make black happy

* This PR impliments the feature request #784.

When a folder is explicit defined in `pyproject.toml` as excluded, all nested data, including subfolder, are excluded. It is no longer neccessary to use the glob `folder/**/*`

* use `Path` instead of `os.path.join` to create string for globbing

* try to fix linting error

* create glob pattern string by concatenating and not using Path

* using `os.path.isdir()`` for checking of explicit excluded name is a folder, because pathlib's `is_dir()` raises in exception under windows of name contains globing characters

* Remove nested data when wildcards where used.

Steps to do this are:
1. expand any wildcard used
2. if expanded path is a folder append  **/* and expand again

* fix linting

* only glob a second time if path is dir

* implement @sdispater 's suggestion for better readability

* fix glob for windows?

* On Windows, testing if a path with a glob is a directory will raise an OSError

* pathlibs  glob function doesn't return the correct case (https://bugs.python.org/issue26655). So switching back to  glob.glob()

* removing obsolete imports

Fixes #1153

Currently Poetry will detect that it is running in a usual virtual env
created with "python -m venv" and will not create an additional env.

This commit extends this logic to Conda, which uses different
environment variables to indicate running in a virtual env.

Conda's "base" env is treated specially to avoid polluting global
namespace.

* Refactor the environment management code

* Improve executable selection when current Python is incompatible

* Allow uploading of wheels with local version identifier

* Check that a git dependency resolves to a revision

A git dependency should be resolved to a full git revision (SHA-1).
When dealing with a git dependency, this is the only way to lock
the dependency in-place (because revisions are immutable).

* Check that a pinned git dependency resolves to a revision

There are three mutually exclusive parameters that can be used to
pin a git dependency: `branch`, `tag`, and `rev`.  Since they all
can be moving targets, they should be resolved to a full git
revision (SHA-1) to ensure a proper in-place lock.

This change highlights bug #1331 and currently fails.

* Make sure a git reference resolves to a revision

Do not lock a git dependency to a named reference but to a full
git revision instead.  This ensures reproducibility and security
as git revisions are immutable.

Fixes: #1331
