Commit Message

Fix perf issue in dd.Series.isin (#4727)

Previously this was slow for large lists/large npartitions for two
reasons:

- The `values` object was part of every task in the graph, increasing
the serialization cost between workers, and traversal cost when
evaluating on a worker.
- The `values` object is usually a builtin python collection (usually a
list), which coupled with the above would significantly slow down our
optimization passes as a large list was traversed once for every
partition.

We now wrap `values` in `delayed`, avoiding both of these problems.

Also expanded test coverage for `isin`, explicitly forbidding a few odd
arguments we don't support.
