fix(xen-api): don't normalize/trim strings in XML-RPC

This applies to both XML-RPC transport and results of XAPI tasks.

Before this commit, all whitespaces (spaces, new lines, etc.) were reduces to
a single whitespaces and leading and trailing whitespaces where removed.

This led to malformed values such as the result of `host.get_server_certificate`.
