Title: Permit the use of & characters in passwords

As per the comments, the HP iLOs support '&' in passwords, whereas this is a special character in XML. ElementTree escapes the & character into & which causes a 'login failed' error.

The closest actual reference I can find from HP on this is in HP advisory document c03221572.
