Translate model names for English
We need a volunteer who could review English translation
(locale/en/foreman.po). We need to "translate" all strings with keys in
the format of
msgid "Hostgroup|Root pass"
These keys are used in all forms and table headers. By default, only the
last element is rendered ("Root pass" in this case) which is not correct
in all cases (in this case we want "Root password").
All these keys are marked with the following comment:
#. "Table name" or "Table name|Column name" for error messages
