Subject: [PATCH] vCenter: fix parsing of HTTP status string (RHBZ#1837328)

vCenter 7 answers with an HTTP/2 status string, so we cannot extract
the status code from it by using fixed positions in that string.
Hence, pick the status code by reading what's after the whitespace.

Tested with vCenter 6.5 and 7.

(cherry picked from commit d2aa82317964d62fcc8dc7b6737773003d04b998)
