localindices methods in conflict with SharedArrays

[henryk-modzelewski]

It seems like there is a conflict between localindices method between SharedArrays and DistributedArrays. Please, see the REPL output below.

help?> SharedArrays.localindices
localindices(S::SharedArray)

Returns a range describing the "default" indices to be handled by the current process. This range should
be interpreted in the sense of linear indexing, i.e., as a sub-range of 1:length(S). In multi-process
contexts, returns an empty range in the parent process (or any process for which indexpids returns 0).

It's worth emphasizing that localindices exists purely as a convenience, and you can partition work on the
array among workers any way you wish. For a SharedArray, all indices should be equally fast for each
worker process.

help?> DistributedArrays.localindices
localindices(d)

A tuple describing the indices owned by the local process. Returns a tuple with empty ranges if no local
part exists on the calling process.

As suggested on discourse, the solution might be to add a function localindices to Base, and have both SharedArrays and DistributedArrays add methods to that function.
