Comment 1 for bug 1748433

Ansible version changed from 2.0 to 2.5 and there is several changes in newer version. The default config of remote_tmp changed from " $HOME/.ansible/tmp" to "~/.ansible/tmp". In my opinion it's better that the charmhelper library handle this parameter to avoid any problem related to this in newer versions. I will submit a patch to charmhelpers shortly.
