Similar to issue #2108, min_alpha is exposed, but not alpha for datashade()

WARNING:root:datashade: 'alpha' will be ignored (not a Parameter).

What were you hoping alpha would do, as an argument to datashade()? Datashader already uses the alpha channel in its own computations, returning RGBA images. ETA: Never mind; it only uses alpha internally when doing count_cat; otherwise alpha is available. In that case, this should be done, just as for min_alpha.
