magodo 92b998c3ab consul config source support 1st-level array
Check whetehr the 1st level encoded json is array or not, to
support 1st level array in consul config.

During debug, i suspected the incapability of arrray is caused by
json reader, so i added test for array. I think it makes no harm
to also check that in.
