Feat: Add support for json resources

[nityanandagohain]

Adds a json column for resources in logs and traces

fixes SigNoz/signoz#8199

We are just writing the string map data here.

So if the key is

"service.name" : "hello"

it will be stored as {"service": {"name":"hello"}

but since we are unsuring that we are writing string map, values containing json won't be affected and will be stored as flattened one. And for resource attributes that will be rarely the case.

---

The QB changes are here SigNoz/signoz#8376 , but will need a plan to rollout i.e we can rollout directly for new users and then move the old ones later.
