feat(forge): allow --verifier custom option

[grandizzy]

Motivation

Closes #9220
Closes #8254
Closes #7466 (no need to pass chain param as it will be retrieved from provider / --rpc-url)
Closes #8100

• allows custom verifiers to be defined as --verifier custom. adds --verifier-api-key for custom verifier keys

Verifier options:
      --verifier <VERIFIER>
          The contract verification provider to use
          
          [default: etherscan]

          Possible values:
          - etherscan
          - sourcify
          - blockscout
          - oklink
          - custom:     Custom verification provider, compatible with Etherscan API

      --verifier-api-key <VERIFIER_API_KEY>
          The verifier API KEY, if using a custom provider
          
          [env: VERIFIER_API_KEY=]

      --verifier-url <VERIFIER_URL>
          The verifier URL, if using a custom provider
          
          [env: VERIFIER_URL=]

• could be passed as cli arg, e.g.

forge create \
  --rpc-url http://localhost:8545 \
  --private-key 0x12345.... \
  src/Counter.sol:Counter \
  --verify \
  --verifier custom \
  --verifier-url http://localhost:8888/api \
  --verifier-api-key 1234

forge verify-contract \
  0x59b670e9fA9D0A427751Af201D676719a970857b \
  --rpc-url http://localhost:8545 \
  --verifier custom \
  --verifier-url http://localhost:8888/api \
  --verifier-api-key 1234

or defined and implicitly taken from foundry.toml config, e.g.

[etherscan]
anvil-hardhat = { key = "1234", url = "http://localhost:8888/api" }

forge create \
  --rpc-url http://localhost:8545 \
  --private-key 0x12345.... \
  src/Counter.sol:Counter \
  --verify

forge verify-contract \
  0x59b670e9fA9D0A427751Af201D676719a970857b \
  --rpc-url http://localhost:8545

• better user feedback for retry error handle, print console warning

Solution

[grandizzy]

I think would be nice to have a --verifier-api-key so custom verifiers args won't need the etherscan keyword at all...
