Merge list of objects with common keys

[jurgenweber]

I have:

              + batched-metrics        = [
                  + {
                      + "bucket" = "manifest"
                      + "name"   = "batched-metrics"
                    },
                  + {
                      + "name"  = "batched-metrics"
                      + "table" = "user"
                    },
                ]

I need:

              + batched-metrics        = 
                  + {
                      + "bucket" = "manifest"
                      + "name"   = "batched-metrics"
                      + "table" = "user"
                    }

Thanks.
