Add a histogram to record how long fetching the system proxy settings takes:
Net.ProxyPollConfigurationTime
On Windows, this corresponds to the duration of WinHttpGetIEProxyConfigForCurrentUser(), which we have seen can run very slowly on some systesm. This histogram tries to gauge the extent of the problem.
BUG=12189
