New Role management module

There is a new role management module placed in the plugins folder:

    plugins/modules/iparole.py

The role module allows to ensure presence or absence of roles and
manage role members.

Here is the documentation for the module:

    README-role.md

New example playbooks have been added:

    playbooks/role/role-is-absent.yml
    playbooks/role/role-is-present.yml
    playbooks/role/role-member-group-absent.yml
    playbooks/role/role-member-group-present.yml
    playbooks/role/role-member-host-absent.yml
    playbooks/role/role-member-host-present.yml
    playbooks/role/role-member-hostgroup-absent.yml
    playbooks/role/role-member-hostgroup-present.yml
    playbooks/role/role-member-privilege-absent.yml
    playbooks/role/role-member-privilege-present.yml
    playbooks/role/role-member-service-absent.yml
    playbooks/role/role-member-service-present.yml
    playbooks/role/role-member-user-absent.yml
    playbooks/role/role-member-user-present.yml
    playbooks/role/role-members-absent.yml
    playbooks/role/role-members-present.yml
    playbooks/role/role-rename.yml

New tests for the module:

    tests/role/test_role.yml
    tests/role/test_role_service_member.yml

tests/external-signed-ca-../external-ca.sh: Password too weak in FIPS…

The password that is used in the script to generate the CA and also sign
the CSR is not strong enough in FIPS mode. In normal mode the password was
ok, though.

In FIPS mode the password needs to have at least one upper, lower, digit
and a special char.

Fix variable name error

Terminology improvements: use allow list.

ipareplica: Fix missing parameters for several modules

The parameters master_host_name, config_setup_ca, dirman_password have not
been set for some modules. Also there was no ldap2 connection within
ipareplica_setup_kra. All this resulted in improper configuration where
for example KRA deployment failed in the end.

A conversion warning in ipareplica_setup_adtrust has also been fixed for
the setup_ca parameter.

Fixes #314 (IPA replica installation failure - DS enabled SSL - second part)

ipa[server,replica]: Fix pkcs12 info regressions introduced with CA-less

With the CA-less patches the types for the pkcs12 infos have been changed
to lists in the modules. This is resulting in a bad conversion from None
to [''] for the parameters. Because of this a normal replica deployment is
failing as [''] is not a valid value.

The install.yml files for ipareplica and also ipaserver have been changed
in the way that the pkcs12 values are checked if they are None. The
parameter will simply be omitted in this case and the parameter in the
module will become None by default.

action_plugins/ipaclient_get_otp: Discovered python needed in task_vars

Ansible is now also supporting discovered_python_interpreter for
action_plugins. task_vars needs to be non Null and contain a setting for
discovered_python_interpreter. The ipaclient_get_otp action_plugin
therefore needed to be adapted.

Fixes ipaservice disable tests.

Due to use of some shell commands that required a Kerberos ticket,
the ipaservice test test_service_disable would no work if a ticket
was not granted before it ran. This patch adresses this issue by
acquiring a ticket for the `admin` user before it is needed, and
destroying the tickets by the end of the test execution.

ipa[user,host]: Fail on duplucate names in the users and hosts lists

ipa[host]group: Fix membermanager unknow user issue

If a unknown membermanager user presence will be ensured, the unknown user
error was ignored. This has been fixed in ipagroup. The code for the error
handling in ipagroup and ipahostgroup has been adapted because of this.

New tests for tests/[host]group/test_[host]group_membermnager.yml have been
added.

Add suppport for changing password of symmetric vaults.

Allows changing passwords of symmetric waults, using a new variable
`new_password` (or the file-base version, `new_password_file`). The
old password must be passed using the `password` or `password_file`
variables that also received new aliases `old_password` and
`old_password_file`, respectively.

Tests were modyfied to reflect the changes.

It was possible to have several entries for names with the hosts and users
lists. This resulted sometimes in errors but also unexpected changes. A new
check has been added to make sure that the names in the users and hosts
lists are unique.

New tests have been added to verify this in the existing files:
- tests/host/test_hosts.yml
- tests/user/test_users.yml

Fixes service disable when service has no certificates attached.

Fix forwardzone issues

This patch allows the modification of the forward zone policy in
an existing DNS Forward Zone, and fixes some issues with `enable`
and `disable` state that prevented correct behavior of `forwardpolicy`.

Adds missing attribute `permission to dnsforwardzone module, that
enable setting `manageby` for the DNS Forwar Zone.

Services without certificates, but with keytabs were not being
disabled. This change allows execution of service_disable if
there is a certificate or if has_keytab is true.

A new test was added to verify the issue:

    tests/service/test_service_disable.yml

This patch modify the was forwarders are configured, using two attributes,
`ip_address` and `port`, instead of IPA API internal string representation
of `IP port PORT`.

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.

Fixes error handling on dnsconfig module.

This fixes reporting errors on dnsconfig module and add some tests
to verify that invalid IP addresses cannot be used as forwarders.
