https://github.com/provectus/kafka-ui/blob/master/kafka-ui-react-app/src/components/Topics/New/CustomParams/customParamsOptions.tsx - file with ALL available custom parameters with default values. Created it myself - I might have missed something - feel free to update

1. update backend topic creation API to handle custom params
   the schema is the following

{..., configs: { ..., customParams: { 'timestamp1': { name: customParamName, value: customParamValue }, 'timestamp2': { name: customParamName2, value: customParamValue2 }, ... }, }, }

2. add validation for custom params(
   no empty values,
   no invalid values(strings for ints, etc),
   no duplicate values
   )

Why do we need ` timestamp in custom params map?
```customParams: { 'timestamp1' ``

@germanosin thats outdated. Custom params now are simply under config = { ... customParams } just with other options
