Watch watches for events happening or that have happened. Both input and output
are streams; the input stream is for creating and canceling watchers and the output
stream sends events. One watch RPC can watch on multiple key ranges, streaming events
for several watches at once. The entire event history can be watched starting from the
last compaction revision.
