[WIP] Add redis storage extension

[pepperkick]

Description:
Add Redis storage extension to utilize it as exporter queue.

Link to tracking Issue:
#31682

Testing:

Did basic functionality testing.

• Had 2 collectors, A and B
• A exports to B with redis queue enabled
• Took down B and sent 100 traces to A
• Ensured 100 entries were in redis
• Started collector B and ensured 100 traces were received by it

Documentation:
TBD

I do have one major concern.

I was able to implement basic setter and getter with Redis. But one of the main of the main feature that I wanted was that multiple collectors could connect to the same Redis DB and during dequeue they can distribute the work.

The way l implemented it before was to add a lock function in exporterhelper (collector v0.70.0) which would create a lock key against the actual key with short TTL. That way a collector can lock a key, process it and then delete it. In case the collector fails, so other collector can pick it up after the lock expires.

Doing the same in the current storage interface will require an additional Lock operation.
