[refactor] Decouple TraceQueryParams from Query in integration tests (#6779)

## Which problem is this PR solving?
- Towards #6765

## Description of the changes
- This PR is a prelude to
#6769. That PR was running
into issues because a JSON type cannot be unmarshalled into the
`pcommon.Map` type. In order to fix that, this PR decouples the `Query`
in the integration test from `TraceQueryParams` so that we can accept
queries as JSON and populate them into the `TraceQueryParams` as we see
fit.

## How was this change tested?
- CI
