Remove broken testnet-verifier

[gbouv]

The testnet-verifier is currently broken for several reasons.

==
First, I run the module and almost immediately run:

./merge_testnet_verifier --ttd 0 --ttd-epoch-limit 0 --verif-epoch-limit 5 --client geth,http://<IP_GETH_NODE>:8545

and it runs the tests, even though we're not yet at epoch 5. I think it should wait for epoch 5 to be reached based on the description of verif-epoch-limit

==
Second, when I add a beacon node:

./merge_testnet_verifier --ttd 0 --ttd-epoch-limit 0 --verif-epoch-limit 5 --client geth,http://<IP_GETH_NODE>:8545 --client lighthouse,http://<IP_LIGHTHOUSE_BEACON>:4000

It loops forever with:

WARN[10-24|14:22:05] Error getting ttd block/slot             client=Lighthouse clientID=0 error="time before genesis"

When I manually kill it with Ctrl+C, before exiting it prints:

CRIT[10-24|14:50:40] Post-Merge Beacon Blocks Produced        client=Lighthouse clientID=0 pass=false extra="0 < 1"
CRIT[10-24|14:50:40] Post-Merge Justified Epochs              client=Lighthouse clientID=0 pass=false extra="0 < 1"
CRIT[10-24|14:50:40] Post-Merge Finalized Epochs              client=Lighthouse clientID=0 pass=false extra="0 < 2"
CRIT[10-24|14:50:40] Post-Merge Epoch Attestation Performance client=Lighthouse clientID=0 pass=false extra="0 < 85"
CRIT[10-24|14:50:40] Post-Merge Epoch Target Attestation Performance client=Lighthouse clientID=0 pass=false extra="0 < 85"
CRIT[10-24|14:50:40] Post-Merge Sync Participation Percentage client=Lighthouse clientID=0 pass=false extra="0 < 85"

All values are at zero.

==
Third, when I pass also a validator node:

./merge_testnet_verifier --ttd 0 --ttd-epoch-limit 0 --verif-epoch-limit 5 --client geth,http://<IP_GETH_NODE>:8545 --client lighthouse,http://<IP_LIGHTHOUSE_BEACON>:4000 --client lighthouse,http://<IP_LIGHTHOUSE_VALIDATOR>:5042

It immediately crashes complaining it can't reach the validator node.

==
Not entirely sure what's happening. Discussing with @parithosh on Discord, it could be that the verifier is confused because it's waiting for TTD to be reached, but here since we're running the network post merge from the start it's never really reached (and we set TTD to zero).
We should also check how the verifier is reading from the beacon and the validator, it seems it's having trouble retrieving the data.

Verified with @parithosh and @marioevz that the best thing to do right now is to remove it: https://discord.com/channels/783719264308953108/969943161264812112/1045035000875200532
