esx: do not store escaped password in esxVI_Context.

Browse Source 
This patch fixes an issue where screenshot API call was failing when
the esx/vcenter password contains special characters such as
apostrophee. The reason for failures was that passwords were escaped
for XML and stored in esxVI_Context which was then passed to raw CURL
API calls where the password must be passed in original form to
authenticate successfully. So this patch addresses this by storing
original passwords in the esxVI_Context struct and escape only for
esxVI_Login call.
