V2 E2E Tests

[ethenotethan]

E2E tests will need to be extended to ensure correctness of interactions with EigenDA V2 protocol. We should:

• Introduce some new V2_ENABLED flag which when presented results in a V2 configuration being loaded. All the existing E2E tests can be re-leveraged for V2
• Introduce V2 specific test cases?

The trickier case will be migration or cross compatibility; ie:

1. Disperse blob to V1 network (!V2_ENABLED) via rollup batcher and kill proxy instance (cert0)
2. Spawn new instance (V2_ENABLED) and disperse blob to EigenDA v2 network (cert1)
3. Sync rollup derivation or inbox reading pipeline from start; sync(cert0, cert1)

This test should enforce that an insecure EigenDA rollup integration can seamlessly start using V2 without any hiccups
