With these settings for server, replica and client it is possible to skip
package installation. This is for example useful if the packages are already
installed. The settings default to yes

The setting ipareplica_no_package_install has been removed.

The ipareplica role is reusing the ipaserver_enable_ipa module. This module
needed some extensions on the server to enable the delayed services and
also to dump DNS configuration (see commit a1287265).
For replica it is not needed to dump the DNS configuration, therefore it is
simply possible to set detup_dns to no to make this module also working
for ipareplica.

This typo has been introduced with 20d25d0d in import_tasks for the
Python 2/3 test.

As the old way to include tasks is deprecated, replace static include
statements with import_tasks and dynamic ones with include_tasks.

Increaded the required ansible version to 2.5.0 to make sure that
include_tasks and import_tasks is working as expected.

Fixes issue #38

This reverts commit 7a76f73b.

It needs to be done as ansible 2.7.1 is now complaining on unknown attribues.

This fixes issue #48: https://github.com/freeipa/ansible-freeipa/issues/48

This is a partly pick of the changes done by pyguy for pull request #28.
The unrelated changed on inventory files have been removed and the change
to the README has been adapted to use the "Supported Distributions" section.

The original commits by pyguy in https://github.com/pyguy/ansible-freeipa
are:

    Ubuntu Support added

commit 9a4a7c84e4af20af27e814aba4fc2c6b8b35ec0f
Author: pyguy <hr.josheghani@gmail.com>

    Ubuntu support added

There is a pull request and also a proposal for ansible be able to limit the
number of concurrent executions for a single task:

- https://github.com/ansible/proposals/issues/129
- https://github.com/ansible/ansible/pull/42528

The keyword is currently named max_concurrent, but might be renamed later
on. If the keyword is present, but not supported by ansible, it will be
simply ignored. Therefore there is no issue right now with adding in here
early.

The ipaclient role is now used instead of ipa-client-install.

custodiainstance.import_dm_password does not support master_host_name post
4.6.90 anymore. A new inspect call has been added to verify if the arg is
supported or not.

custodia needs to be used here with newer IPA versions (introduced with 4.6.4).
With this master_host_name does is not supplied to custodia.import_dm_password
as an arguemtn anymore.

The use of IPA versions to determine if get_custodia_instance should be
used was not optimal as the patch that introduced this has been back-ported
to the EL-7 package with verion 4.5.4. As get_custodia_instance was not
available before we can simply check if get_custodia_instance exists in
custodiainstance.

A new Fedora-27 ditribution specific file has been added. Additionally
ipareplica_packages_adtrust has been updated in all files to contain
[free]ipa-server-trust-ad.

With IPA 4.7 bigger changes have been introduced

Changes:
- Use of timeconf and chrony instead of ntpconf and ntpd.
- custodia instance needed for ca and kra
- Use of create_ipa_conf with changed setting in setup_http for install_http,
  reverted back afterwards.

Affected files:
- ipareplica/library/ipaserver_enable_ipa.py
- ipareplica/library/ipaserver_master_password.py
- ipareplica/library/ipaserver_setup_ntp.py

The _pkinit_pkcs12_info var seems not to be needed for now. Will be removed
in a following cleanup.

- Do not register a change in the playbook run when registering the
  variable checking for whether or not Python 3 imports work

The support for external cert files is not complete yet.

Please have a look at the example inventory file inventory/hosts.replica and
also the install and uninstall playbook files install-replica.yml and
uninstall-replica.yml
