zypper_repository: Improve .repo file idempotency (#3474)

* If repo option points to .repo file, download for later parsing

* Parse downloaded .repo file content (ini format)

* Validate downloaded file, map values to repodata, workaround to ignore old .repo related code

* Integration Test adjusted to install python package 'requests' first

* Revert "Integration Test adjusted to install python package 'requests' first"

This reverts commit 0d18352c2238d098831ba6d59b66e731fa8f0cd9.
Not allowed to introduce new dependencies at this point, module_utils usage required

* Remove python 'requests' dependency, using 'fetch_url' and 'to_text' from 'ansible.module_utils' instead

* Prefer alias (name) if given instead repo (url)

* If gpgkey was given in .repo file ensure key get automatically imported

* ConfigParser Import made Python2 compatible

* New .repo code moved below existing run-time parameters checks to keep previous logic

* Obsolete workaround removed

* two pylint/pep8 errors fixed

* name added to autorefresh assert

* Missing assert for 'Delete test repo' added

* name added to priority option assert

* name added to check repo is updated by url assert

* name added to check repo is updated by name assert

* name added to check add a repo by releasever assert

* name added to check remove added repo assert

* name added to check add a repo by basearch assert

* name added to check remove added repo #2 assert

* Bugfix to avoid 'KeyError' Exception in if statements

* Refactoring of configparser related code, usage of module_utils, py2 compatibility

* Removal of some leftover from earlier testing

* Integration tests for add/remove repositories by url to .repo file added

* Additional name added to list of test repos that has to be removed

* Test added to verify cleanup of local .repo file after removal via zypper

* Changelog fragment related to PR #3474 added

* yamllint error resolved

* Refactoring to reduce indentation and removal of else statements

* Integration tests added for loading .repo file from local path

* Test .repo file added

* Dependency to setup_remote_tmp_dir added

* New entry added to 'remove repositories added during test'

* Support for .repo file from local path

* Changelog: Ref to https://github.com/ansible-collections/community.general/issues/3466 added
