ipaserver/library/ipaserver_setup_ca.py: Fix bug introduced with ca-less PR

The ca-less PR introduced a bug when http_ca_cert is not set. The test
for loading the certificate is testing for None, but the string will only
be empty in this case.

Galaxy refuses to import a collection that has license and license_file set
in galaxy.yml. Therefore license_file has been removed.

Fixes attempt to create rules with members when category is `all`.

Current implementation of hbacrule and sudorule allow for a new rule
creation script to be partialy successful when a member is provided and
the respective member category is set to `all` (either users, hosts,
services, commands, and their group counterparts).

Since the creation of the rule is independent of the adittion of members,
the rule is succesfully created, but member addition fails, leaving with
a created rule that has no members on it.

This patch fixes both modules by verifying if user, host, service or
commands (and groups of members) are being added if the corresponding
category is set to `all`, when the state is `present` and the action is
not `member`. If so, it fails before the rule is created.

New dnsrecord management module.

Vault add state retrieved

This patch add support for the attributes `maxtostname` and
`ca_renewal_master_server` attributes that were missing and
also provide a more complete set of tests.

This change split vault tests in several files, organized by vault
type and operation (vault vs. member) so that it is easier to add
new tests for issues and verify if tests are missing.

This patch adds support for retrieving data stored in an IPA vault by
adding a new valid state for ipavault: `retrieved`.

To allow the retrieval of data from assymetric vaults, the attributes
`private_key`, `private_key_files` and `out` were also added to the
module.

The private key files, `private.pem`, should be paired with the already
existing `public.pem` public key files.

Tests were updated to reflect changes and two new playbooks were added:

    playbooks/vault/retrive-data-asymmetric-vault.yml
    playbooks/vault/retrive-data-symmetric-vault.yml

This patch fixes handling of password and public_key files, parameter
validation depending on vault type, usage of `salt` attribute and data
retrieval.

Tests were updated to reflect the changes.

New example playbooks are added:

    playbooks/vault/vault-is-present-with-password-file.yml
    playbooks/vault/vault-is-present-with-public-key-file.yml

A group membership manager is a user or a group that can add members to
a group or remove members from a hostgroup.

This is related to https://pagure.io/freeipa/issue/8114

New parameters have been added to the module:
- `membermanager_user`: List of member manager users assigned to this
  group. Only usable with IPA versions 4.8.4 and up.
- `membermanager_group`: List of member manager groups assigned to this
  group. Only usable with IPA versions 4.8.4 and up.

These parameters behave like member parameters.

A new test has been added:

There is a new dnsrecord managem module placed in the plugins folder:

    plugins/modules/ipadnsrecord.py

The dnsrecord module allows management of DNS records and is as compatible
as possible with the Ansible upstream `ipa_dnsrecord` module, but provide
some other features like multiple record management in one execution,
support for more DNS record types, and more.

Here is the documentation for the module:

    README-dnsrecord

New example playbooks have been added:

    playbooks/dnsrecord/ensure-dnsrecord-is-absent.yml
    playbooks/dnsrecord/ensure-dnsrecord-is-present.yml
    playbooks/dnsrecord/ensure-presence-multiple-records.yml
    playbooks/dnsrecord/ensure-dnsrecord-with-reverse-is-present.yml

    playbooks/dnsrecord/ensure-A-and-AAAA-records-are-absent.yml
    playbooks/dnsrecord/ensure-A-and-AAAA-records-are-present.yml
    playbooks/dnsrecord/ensure-CNAME-record-is-absent.yml
    playbooks/dnsrecord/ensure-CNAME-record-is-present.yml
    playbooks/dnsrecord/ensure-MX-record-is-present.yml

    playbooks/dnsrecord/ensure-TXT-record-is-present.yml
    playbooks/dnsrecord/ensure-URI-record-is-present.yml

New tests for the module can be found at:

    tests/dnsrecord/test_dnsrecord.yml
    tests/dnsrecord/test_compatibility_with_ansible_module.yml
    tests/dnsrecord/test_dnsrecord_full_records.yml

It should be `Playbook to handle server configuration` instead of
`Playbook to handle users`.

This patch adds variable `smb`, that can be used when adding a new
service, and creates a SMB service (cifs) with an optional
`netbiosname`.

This patch changes auth_ind variable to receive a list of values
instead of a single one, so that more than one value can be set
at once.

Tests have been updated to reflect the change.

When using a variable that is invalid for a given action, the `action`
was not being displayed in the error message, leading to a poor user
experience.
