ansible_freeipa_module: Set KRB5CCNAME for api_connect (non root)

Add flake8 and pydocstyle lints

Not delete keytab when ipaclient_on_master is true

In the case that the admin password has been set and become was not set
the call to backend.connect in api_connect failed. The solution is simply
to set os.environ["KRB5CCNAME"] in temp_kinit after kinit_password has
been called using the temporary ccache. os.environ["KRB5CCNAME"] is not
used automatically by api.Backend.[ldap2,rpcclient].connect. Afterwards
os.environ["KRB5CCNAME"] is unset in temp_kdestroy if ccache_name is not
None.

Fixes: #249 (Kerberos errors while using the modules with a non-sudoer user)

Galaxy fix

The old name was galaxyify-playbook.py instead of galaxyfy-playbook.py

The namespace and colleciton name have been hard coded. Now variables are
used for them. The project prefix and collection prefix are now passed to
galaxyify-playbook.py.

krb was set, but not used afterwards. Therefore it can be removed.

The installer_ccache parameter is used in the module. The ccache parameter
was only set, but not used at all.

Sudorule test enhancement

The use of "default: idstart+199999" in the description of the idmax
parameter was resulting in the galaxy import error:

  Cannot parse "DOCUMENTATION": mapping values are not allowed here in
  "<unicode string>", line 52, column 58: ... value for the IDs range
  (default: idstart+199999)

The ":" has simply been removed to fix this issue.

Galaxy does not like the use of the extra "-1" release tag.

Fixes: #236 (Can't install via Galaxy)

Fixed a bug in AnsibleFreeIPAParams

When accessing an instance of AnsibleFreeIPAParams with .get the obj was
by-passing the call to _afm_convert which was the primaty reason why it
was created.

Also the class now extends Mapping instead of dict.

Added aliases for in dnszone module arguments

Add admin password to the ipadnsconfig module tests.

This change avoid the need to obtain an admin TGT on the testing target before running the tests.

Handle RuntimeError in fail_json

ipa[server,replica,client]: setup_logging wrapper for standard_logging setup

DNSZone module

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

    plugins/modules/ipadnszone.py

    The dnszone module allows to manage DNS zones.

    Here is the documentation for the module:

    README-dnszone.md

    New example playbooks have been added:

    playbooks/dnszone/disable-zone-forwarders.yml
    playbooks/dnszone/dnszone-absent.yml
    playbooks/dnszone/dnszone-all-params.yml
    playbooks/dnszone/dnszone-disable.yml
    playbooks/dnszone/dnszone-enable.yml
    playbooks/dnszone/dnszone-present.yml

    New tests for the module:

    tests/dnszone/test_dnszone.yml
    tests/dnszone/test_dnszone_mod.yml

ipareplica_prepare: Fix module DOCUMENTATION

The import of ansible_ipa_server, ansible_ipa_replica and ansible_ipa_client
might result in a permission denied error for the log file. It seems that
for collections the module utils seem to be loaded before the needed
permissions are aquired now.

The fix simply adds a wrapper for standard_logging_setup that is called in
all the modules of the server, replica and client roles to do the loggin
setup as one of the first steps of the module execution and not before.

The documentation contains the pramaters several times. Reducing the list
to one. Also fixed a typo in options key.

Gracefully handle RuntimeError raised during parameter validation
in fail_json.

Fixes: #115

This patch adds tests for some options that were not being tested, and
enhances test behavior.

Add dnsforwardzone module

Fixes behavior for host module attribute `reverse`

Due to setting aaaa_extra_create_reverse or a_extra_create_reverse when not
needed, host module fails to add a host with reverse address. This patch
fixes the behavior  by only adding *_extra_create_reverse when needed.

New DNSConfig management module

Add documentation of missing variables for sudorule.
