Use IPAAnsibleModule and ipamodule_base_docs in the templates of
utils/new_module.

ipaadmin_password lines in the examples have been added, ipaadmin_
variables are handled by IPAAnsibleModule, ansible_module.params_get is
used to get the parameters and ansible_module.ipa_connect is used to
simplify the module.

ipamodule+member.py.in is additionally using gen_add_list and
gen_intersection_list to reduce the command calls to the changes only.
