Correctly handle .repo files in zypper_repository module

Before the changes, removing a repository required a repo url. This shouldn't be required since zypper allows removing a repo based on its alias (mapped to name in this module).

The name variable was always required, which is misleading since repofiles provide their own alias. So a runtime check was added to avoid this confusion.

Additionaly, running this module on .repo files weren't idempotent. e.g

Before:
$ ./hacking/test-module -m library/packaging/zypper_repository -a "repo=http://download.opensuse.org/repositories/devel:/languages:/python/SLE_11_SP3/devel:languages:python.repo name=foo"
{"repo": "http://download.opensuse.org/repositories/devel:/languages:/python/SLE_11_SP3/devel:languages:python.repo", "state": "present", "changed": true}
$ ./hacking/test-module -m library/packaging/zypper_repository -a "repo=http://download.opensuse.org/repositories/devel:/languages:/python/SLE_11_SP3/devel:languages:python.repo name=foo"
{"msg": "Repository named 'devel_languages_python' already exists. Please use another alias.\n", "failed": true}

After:
$ ./hacking/test-module -m library/packaging/zypper_repository -a "repo=http://download.opensuse.org/repositories/devel:/languages:/python/SLE_11_SP3/devel:languages:python.repo"
{"repo": "http://download.opensuse.org/repositories/devel:/languages:/python/SLE_11_SP3/devel:languages:python.repo", "state": "present", "changed": true}
$ ./hacking/test-module -m library/packaging/zypper_repository -a "repo=http://download.opensuse.org/repositories/devel:/languages:/python/SLE_11_SP3/devel:languages:python.repo"
{"repo": "http://download.opensuse.org/repositories/devel:/languages:/python/SLE_11_SP3/devel:languages:python.repo", "state": "present", "changed": false}

Fix #8047

Ensure that json is returned when only updating the cache and in check mode
Make 'compress' optional
Ensure version is a string
Correct typo
Fix the name of the package that provides apt-add-repository on Ubuntu
Added setting of the health_check options on an existing ASG
Update lineinfile
New option for route53: retry_interval

The current (hard-coded) retry interval of 500 seconds can cause ansible to have excessive run-times in the case of many domains. `retry_interval` provides a way to customize the wait between retries of calls to route53.
Set Jinja2's keep_trailing_newline=True in template_from_string.

Without this setting, the newline idempotence of scalar strings changes depending on whether
or not they contain any Jinja2 template blocks.
Fix "TypeError: group id must be integer" if groupid passed in for group
key
Fix EC2_TAG module output structure when listing tags
portage: default exit (not fail) if sync=yes in check mode

Pagerduty has advocated not using ansible for certain sizes of infrastructure.  This module is removed until this is corrected.
