DataArray.__repr__ should parse as a single entity

[davclark]

Simple DataArray repr's would ideally pass as python code which would yield an equivalent object. It should always visually parse as a "single" python object. Right now it looks like a DataArray object followed by a tuple on the following line. e.g.:

DataArray([[[-1.3685536 , -0.87802346,  1.12533207, -0.50299773],
        [ 0.38960639,  0.42815709, -1.23987688,  1.16147007]],
       [[ 0.64110261, -0.68083629, -1.50314814,  0.42519773],
        [ 0.15450664,  1.08758205,  0.85730028,  0.73189326]],
       [[-0.10893355,  0.36861978, -1.62114425, -0.09202748],
        [ 0.99384913, -0.67653663,  0.16258059, -1.44996171]]])
('x', 'y', 'z')

could become:

DataArray([[[-1.3685536 , -0.87802346,  1.12533207, -0.50299773],
        [ 0.38960639,  0.42815709, -1.23987688,  1.16147007]],
       [[ 0.64110261, -0.68083629, -1.50314814,  0.42519773],
        [ 0.15450664,  1.08758205,  0.85730028,  0.73189326]],
       [[-0.10893355,  0.36861978, -1.62114425, -0.09202748],
        [ 0.99384913, -0.67653663,  0.16258059, -1.44996171]]], 
    labels=('x', 'y', 'z'))
