Expose unredirected_headers on maven_artifact (#4812) (#4994) 
* Expose unredirected_headers to module

In some cases, when the initial request returns a redirect and we want
to follow it to get the artifact, we might not want to include certain
headers in the redirection request. Specially headers like
Authorization and Cookies.
Or perhaps the redirect server returns a 400 because it included some
unexpected headers.
Fetch url already supports this feature, but it was being shadowed by
maven_artifact. In here we just expose it.

* Fix Linting errors

* Applied Comments

 - Specified version added
 - Changed description of unredirected_headers

* Check for ansible version

If it's 2.11 or older, we ignore unredirected_headers, otherwise we use
it, as fetch_url has them

* Applied comments

- Removed duplicated code in the call of fetch_url. Used kwargs instead
- Added check if unredirected_params is not empty and the fetch_url
  function does not support it
- Changed function that checks for ansible version
- Removed unused import

* Remove 2.11 breaking change

Made default only for ansible-core version 2.12 and above, but for keep
it empty for ansible-core version 2.11 and below.
Also include the following changes:
  - change doc to use C() on the function description
  - changed doc to use ansible-core instead of Ansible

* Changes in description for readability

* Add changelog fragment

* Change description changelog fragment

(cherry picked from commit a2677fd051)

version if one is not available.
author: "Chris Schmidt (@chrisisbeef)"

description:
- The URL of the Maven Repository to download from.
- Use s3://... if the repository is hosted on Amazon S3, added in version 2.2.
- Use file://... if the repository is local, added in version 2.6
default: https://repo1.maven.org/maven2

headers:
description:
- Add custom HTTP headers to a request in hash/dict format.
type: dict
force_basic_auth:
description:
- httplib2, the library used by the uri module only sends authentication information when a webservice
responds to an initial request with a 401 status. Since some basic auth services do not properly
send a 401, logins will fail. This option forces the sending of the Basic authentication header
upon initial request.
default: 'no'
type: bool
version_added: '0.2.0'

default: present
choices: [present,absent]
timeout:
type: int
description:
- Specifies a timeout in seconds for the connection attempt
default: 10
validate_certs:
description:
- If C(no), SSL certificates will not be validated. This should only be set to C(no) when no other option exists.
type: bool
default: 'yes'
client_cert:
description:
- PEM formatted certificate chain file to be used for SSL client authentication.
- This file can also include the key as well, and if the key is included, I(client_key) is not required.
type: path
version_added: '1.3.0'
client_key:
description:
- PEM formatted file that contains your private key to be used for SSL client authentication.
- If I(client_cert) contains both the certificate and key, this option is not required.
type: path
version_added: '1.3.0'
keep_name:
description:
- If C(yes), the downloaded artifact's name is preserved, i.e the version number remains part of it.
- This option only has effect when C(dest) is a directory and C(version) is set to C(latest) or C(version_by_spec)
is defined.
type: bool
default: 'no'
verify_checksum:
type: str
description:
- If C(never), the MD5/SHA1 checksum will never be downloaded and verified.
- If C(download), the MD5/SHA1 checksum will be downloaded and verified only after artifact download. This is the default.
- If C(change), the MD5/SHA1 checksum will be downloaded and verified if the destination already exist,
to verify if they are identical. This was the behaviour before 2.6. Since it downloads the checksum before (maybe)
downloading the artifact, and since some repository software, when acting as a proxy/cache, return a 404 error
if the artifact has not been cached yet, it may fail unexpectedly.
If you still need it, you should consider using C(always) instead - if you deal with a checksum, it is better to
use it to verify integrity after download.
- C(always) combines C(download) and C(change).
required: false
default: 'download'
choices: ['never', 'download', 'change', 'always']
checksum_alg:
type: str
description:
- If C(md5), checksums will use the MD5 algorithm. This is the default.
- If C(sha1), checksums will use the SHA1 algorithm. This can be used on systems configured to use
FIPS-compliant algorithms, since MD5 will be blocked on such systems.
default: 'md5'
choices: ['md5', 'sha1']
version_added: 3.2.0
unredirected_headers:
type: list
elements: str
version_added: 5.2.0
description:
- A list of headers that should not be included in the redirection. This headers are sent to the fetch_url C(fetch_url) function.
- On ansible-core version 2.12 or later, the default of this option is C([Authorization, Cookie]).
- Useful if the redirection URL does not need to have sensitive headers in the request.
- Requires ansible-core version 2.12 or later.
