java_keystore: add certificate_path and private_key_path options (#2230)
* java_keystore: add `certificate_path` and `private_key_path` options

* Update DOCUMENTATION and EXAMPLES accordingly.
* Refactor integration tests to play the same tasks twice.
* Add a changelog fragment (minor_changes).

refactor DOCUMENTATION

* Add useful info for better understanding of what options allow
  keystore regeneration on the fly, and what other options lead the
  module to fail, if their values change.
* Fix indentation and tenses.
* Add myself as author.

* readability-related stuff + changelog fragment

description:
- Bundle a x509 certificate and its private key into a Java Keystore in JKS format.
options:
name:
description:
- Name of the certificate in the keystore.
- If the provided name does not exist in the keystore, the module fails.
This behavior will change in a next release.
type: str
required: true
certificate:
description:
- Content of the certificate used to create the keystore.
- If the fingerprint of the provided certificate does not match the
fingerprint of the certificate bundled in the keystore, the keystore
is regenerated with the provided certificate.
- Exactly one of I(certificate) or I(certificate_path) is required.
type: str
certificate_path:
description:
- Location of the certificate used to create the keystore.
- If the fingerprint of the provided certificate does not match the
fingerprint of the certificate bundled in the keystore, the keystore
is regenerated with the provided certificate.
- Exactly one of I(certificate) or I(certificate_path) is required.
type: path
version_added: '3.0.0'
private_key:
description:
- Content of the private key used to create the keystore.
- Exactly one of I(private_key) or I(private_key_path) is required.
type: str
private_key_path:
description:
- Location of the private key used to create the keystore.
- Exactly one of I(private_key) or I(private_key_path) is required.
type: path
version_added: '3.0.0'
private_key_passphrase:
description:
- Passphrase used to read the private key, if required.
type: str
version_added: '0.2.0'
password:
description:
- Password that should be used to secure the keystore.
- If the provided password fails to unlock the keystore, the module
fails. This behavior will change in a next release.
type: str
required: true
dest:
description:
- Absolute path of the generated keystore.
type: path
required: true
force:
description:
- Keystore is created even if it already exists.
type: bool
default: 'no'
owner:
description:
- Name of the user that should own jks file.
required: false
group:
description:
- Name of the group that should own jks file.
required: false
mode:
description:
- Mode the file should be.
required: false
requirements:
- openssl in PATH
- keytool in PATH

extends_documentation_fragment:
- files
seealso:
- module: community.general.java_cert
notes:
- I(certificate) and I(private_key) require that their contents are available
on the controller (either inline in a playbook, or with the C(file) lookup),
while I(certificate_path) and I(private_key_path) require that the files are
available on the target host.
