feat: add support for vector sets (#2998)

* wip

* improve the vadd api

* resp3 tests

* fix some tests

* extract json helper functions in client package

* use transformJsonReply

* remove the CACHEABLE flag for all vector set commands

currently, client side caching is not supported
for vector set commands by the server

* properly transform vinfo result

* add resp3 test for vlinks

* add more tests for vrandmember

* fix vrem return types

* fix vsetattr return type

* fix vsim_withscores

* implement vlinks_withscores

* set minimum docker image version to 8

* align return types

* add RAW variant for VEMB -> VEMB_RAW

* use the new parseCommand api
