Andrew Dunham 93cd2ab224 util/singleflight: add DoChanContext ...

This is a variant of DoChan that supports context propagation, such that
the context provided to the inner function will only be canceled when
there are no more waiters for a given key. This can be used to
deduplicate expensive and cancelable calls among multiple callers
safely.
