tasks.create_tmpfiles_dirs only needs IPAAPI_USER as an argument for
version 4.5.4. For 4.5 there is no support for arguments.
IPAAPI_USER is therefore only needed for 4.5.4 in
module_utils/ansible_ipa_server.py

Replace custom file_exists() and dir_exists() functions with proper
functions from Python's stdlib.
The change also gets rid of pylint's invalid bad-python3-import error,

options.kasp_db_file is used in dns.install_check if options.dnssec_master
is enabled. kasp_db_file defauts to None and is only a supported option in
the post deployment ipa-dns-install script. Therefore it is suffient to
set it to None.
forward_policy needs to be None for the DNS check for proper initialization
if the user is not providing another forward_policy value. forward_policy will
be set in the DNS check.
no_dnssec_validation is enabled in the DNS check if the forwarders do not
provide DNSSEC validation. Therefore this needs to be handed over to the dns
installation later on.
New return values for forward_policy and no_dnssec_validation have been added
to the ipaserver_test module.
These global variables are initialized in the dns module in the
dns.install_check function. The settings are needed to be able to do a
proper dns setup in the ipaserver_setup_dns ansible module.
