Allowed asterisk character in the request body

[OlegChuev]

There is a known issue with sending requests to CloudStack where the asterisk * character is not handled properly by the ACS:
apache/cloudstack-cloudmonkey#154

If you have API calls which contain * (asterisk) characters, you will need to add the option “safe = ‘’” for the URL encoding. The reason is that Python’s urllib will encode * characters by default, while CloudStack’s internal encoder does not encode them; this results in an authentication failure for your API call. In the above you would replace “urllib.quote_plus(request[k])” with “urllib.quote_plus(request[k], safe=’’)”.

Footprints:

The CGI.escape does not have a safe parameter, causing the * character to be correctly encoded (into %2A), but this value isn't parsed correctly on the ACS side. This results in the error "Status 401: unable to verify user credentials and/or request signature" when body contains * character
