[v2][storage] Implement read path for v2 storage interface (#6170)

## Which problem is this PR solving?
- Towards #5079

## Description of the changes
- Implemented the read path for the v2 storage interface. This path
currently just wraps a v1 span reader and exposes a static method to
access the v1 reader.
- Change the jaeger query extension to initialize a v2 storage factory
and obtain the v1 span reader from it.
- This will unblock the development of more efficient v2 storage
implementations, like ClickHouse.

## How was this change tested?
- Added unit tests for new functionality

## Checklist
- [x] I have read
