Some errors have been printed to the error log only and fail_json only got
an empty string as error message. This made the causes of the errors hard
to get.

The variables dirsrv_cert_name, dirsrv_pin, http_cert_name, http_pin,
pkinit_cert_name and pkinit_pin have not been initialized properly.

These two varibles in the dns binding are initialized in the installation
check in the install_check parts of ipareplica_prepare and used later on
in the dns configuration in ipareplica_setup_dns.

There is a new setting for the ipareplica role:

ipareplica_pki_config_override

The description of ipaclient_on_master in the ipaclient README was
providing the information that the flag is also used for relicas. This
is not correct and has been removed.

dnsok has been used unitialized in the compatilbility code without sssd.

All module and module_utils scripts have been adapted to be able to only
import the symbols that are really needed and used.

Fixed wrong path to CheckedIPAddress class

If members are added to or removed from a not existing group, an
error is printed.

When OTP is used for installation of a client or the client part of
a replica and also there is no DNS record for the client, then
ipaclient_get_otp fails in the host_add call.

With the force mode the host_add call will ignore the missing DNS
record and will properly add the host. The host information and also
the DNS record will be updated while deploying the client according
to the given settings.

Fixes: #74 (ipaclient fails when ipaclient_use_otp is true and client ..)

Since 4.7.1 it is needed to use CustodiaModes.FIRST_MASTER instead of
CustodiaModes.MASTER_PEER for the get_custodia_instance.

This has been fixed already in ipaserver_setup_ca and also
ipaserver_setup_custodia, but was missed in ipaserver_setup_kra.

Fixes: #92 (KRA install fails in tasks: [ipaserver : Install - Setup KRA])

ansible-lint does not like to have tasks without names. The comments have
been adapted and transformed into name tags.

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

  plugins/modules/ipagroup.py

The group module allows to add, remove, enable, disable, unlock und undelete
groups.

The group module is as compatible as possible to the Ansible upstream
`ipa_group` module, but addtionally offers to add users to a group and also
to remove users from a group.

Here is the documentation for the module:

  README-group.md

New example playbooks have been added:

  playbooks/user/add-groups-to-group.yml
  playbooks/user/add-user-to-group.yml
  playbooks/user/add-group.yml
  playbooks/user/delete-group.yml

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

  plugins/modules/ipauser.py

The user module allows to add, remove, enable, disable, unlock und undelete
users.

The user module is as compatible as possible to the Ansible upstream
`ipa_user` module, but addtionally offers to preserve delete, enable,
disable, unlock and undelete users.

Here is the documentation for the module:

  README-user.md

New example playbooks have been added:

  playbooks/user/add-user.yml
  playbooks/user/delete-user.yml
  playbooks/user/enable-user.yml
  playbooks/user/disable-user.yml
  playbooks/user/delete-preserve--user.yml
  playbooks/user/undelete-user.yml

date_format parses the supported date formats and creates a datetime object.

compare_args_ipa compares generated args with args returned by IPA command
find_ functions.

sync_time is not using options anymore, but has two new arguments. These
are ntp_servers and ntp_pool. The options argument is not used anymore.

This requires to use inspect on sync_time to be able to detect if the old
or the new function is available.

The call for get_time_source has been added, but is documented out as the
call is only useful in interactive mode.

ipaserver_test now returns ntp_servers and ntp_pool, which are then used
for ipaserver_setup_ntp.

If kinit_password call failed because of wrong password or even because
kinit was not found, there was a very unspecific error message. Now these
errors will be properly reported.

Fixes: RHBZ#1727277

Add Information about needed /usr/bin/kinit on the controller when OTP is used

Add Information about needed /usr/bin/kinit on the controller when OTP is used

The raises of RuntimeError, ValueError and ScriptError are currently not
properly handled in ipaserver_prepare. This results in a trace back error
shown in Ansible instead of only showing the error message.

This happened for example if a nameserver is in /etc/resolv.conf that is
not reachable.

The use of password will conflict with the user password setting and is
not really descriptive. ipaadmin_principal and ipaadmin_password are also
used in the roles.

There are currently only external signed CA tests:

external-signed-ca-with-automatic-copy
external-signed-ca-with-manual-copy

This adds support for the --external-ca option to ipaserver. Lots of
additional tests and checks from ServerInstallInterface.__init__ have
been added to ipaserver_test. Also duplicate tests cna checks have been
removed.

Installer settings in ansible_ipa_server module_util are now also set
to the defaults that are used in Installable, ServerInstallInterface,
ServerMasterInstall, ADTrustInstallInterface and Uninstall.

The /root/ipa.csr file generated on the node in ca.install_step_0 will
be copied to the controller as "{{ inventory_hostname }}-ipa.csr".

The new task file copy_external_cert.yml has been added to copy the
generated certificate defined in ipaserver_external_cert_files to the node
to continue with ca.install_step_1.

The tasks/install.yml file has been adapted to make sure that the steps
that will be done in step two will be skipped after step one has been
done.

This is not needed and will calm down ansible-lint, which is not able
to handle the extra tasks folder prefix.
