Add defaults for owner/group/mode on pki_install_host

Reverts the default user/group from
I4a90479261b2721c08e9034fbae0d56de9308676

Adds global default options so user/group etc can
be overridden on the setup host

Some cases of 'omit' for file modes are changed to a
role-defined default which will override any system umask
preferences.
