> 1. Introduce two representations for LogicalType
> Compact one (using asSerializableString):
> {code}
> // compact one
> outputType: "ROW<i INT, s VARCHAR(2147483647)>"
> // full one for all kinds of logical types (time attributes, char(0), inline structured, etc.)
> outputType: {
>   "root" : "ROW",
>   "nullable" : true,
>   "fields" : [ {
>     "i" : "INT"
>   }, {
>     "s" : "VARCHAR(2147483647)"
>   }]
> }
> {code}
> 2. Drop support of legacy types and symbol classes which should not be part of the plan
> 3. Rework DataView support (shorten, remove concrete classes, support any external type in accumulators)
> 4. Implement a DataTypeJsonDeSerializer
> 5. Replace RelDataTypeJsonDeSerializer with LogicalTypeJsonDeSerializer
