Merge master into develop (#2070)

* Fix Github actions cache issues (#1908)

* Fix case of `-f` flag

* Make it clearer what options to pass to `--format`

* fix (masonry.api): `get_requires_for_build_wheel` must return additional list of requirements for building a package, not listed in `pyproject.toml` and not dependencies for the package itself (#1875)

fix (tests): adopted tests

* Lazy Keyring intialization for PasswordManager (#1892)

* Fix Github Actions cache issues (#1928)

* Avoid nested quantifiers with overlapping character space on git url parsing (#1902 (#1913)

* fix (git): match for `\w` instead of `.` for getting user

* change (vcs.git): hold pattern of the regex parts in a dictionary to be consistent over all regexs

* new (vcs.git): test for `parse_url` and some fixes for the regex pattern

* new (vcs.git): test for `parse_url` with string that should fail

* fix (test.vcs.git): make flake8 happy

* fix: correct parsing of wheel version with regex. (#1932)

The previous regexp was only taking the first integer of the version number,
this presented problems when the major version number reached double digits.

Poetry would determine that the version of the dependency is '1', rather than,
ie: '14'. This caused failures to solve versions.

* Fix errors when using the --help option (#1910)

* Fix how repository credentials are retrieved from env vars (#1909)

# Conflicts:
#	poetry/utils/password_manager.py

* Fix downloading packages from Simplepypi (#1851)

* fix downloading packages from simplepypi

* unused code removed

* remove unused imports

* Upgrade dependencies for the 1.0.3 release (#1965)

* Bump version to 1.0.3 (#1966)

* Fix non-compliant Git URL matching

RFC 3986 § 2.3 permits more characters in a URL than were matched. This
corrects that, though there may be other deficiencies. This was a
regression from v1.0.2, where at least “.” was matched without error.

* Update README.md "Updating Poetry"

Currently the note in "Updating Poetry" is different from the one below in "Enable tab completion for Bash, Fish, or Zsh". This MR is to make them more consistent.

* init: change dev dependency prompt

* Fix CI issues (#2069)
