feat: support vectorset (#3375)

* feat: support vectorset

* fix: char encoding error

* use `any` instread of `interface{}`

* update vectorset API

Signed-off-by: fukua95 <fukua95@gmail.com>

* refact: MapStringFloat64Cmd -> VectorInfoSliceCmd

Signed-off-by: fukua95 <fukua95@gmail.com>

* update:

* the type of vector attribute: string -> VectorAttributeMarshaller
* Add a new API VRemAttr
* mark the APIs are experimental

Signed-off-by: fukua95 <fukua95@gmail.com>

* trigger CI again

Signed-off-by: fukua95 <fukua95@gmail.com>

* rename a API: VRemAttr -> VClearAttributes

Signed-off-by: fukua95 <fukua95@gmail.com>

* add test

Signed-off-by: fukua95 <fukua95@gmail.com>

* feat(vectorset): improve VSetAttr API and add comprehensive test suite

- Simplify VSetAttr to accept interface{} with automatic JSON marshalling
- Remove VectorAttributeMarshaller interface for simpler API
- Add comprehensive unit tests for all vectorset commands
