Research direction
Start by locating local.maps.Distribution and the code paths that construct distributions from arrays. Determine how an existing distribution can provide defaults while new_shape, new_dist, and new_grid_shape override them, and check whether global communication is required. Done means a new local Distribution can be created from an existing one with those changes supported.

Description
We should make it easier to make a new local Distribution -- perhaps allow creating a new distribution from an existing distribution.
This comes up when a new local arrays are created that don't match the distribution of the originating array -- perhaps the local shape changes, or the local ndims. local.maps.Distribution could have a classmethod like from_distribution that would take an existing distribution for the defaults and allow passing in new_shape, new_dist and new_grid_shape args that would set the appropriate values. There may need to be global communication to support this.
