A large number of zero byte load events are for cancelled channels, however there is no information about why these channels have been cancelled. Given that all channels nowadays have a canceled reason, this patch adds that reason to the telemetry ping. This member appears to not be used very frequently at the moment, with the only consumers I could find being in tests or network logs. Looking at the callers of `CancelWithReason` I was unable to find any callers which passed a non-literal string, so I believe it shouldn't contain PII, though there doesn't appear to be a mechanism in place to prevent that changing in the future.
