Tracking: EXP-0001

[onbjerg]

We want to add the following endpoints for experiment 1 on AlphaNet to facilitate gas sponsoring of EIP-7702 delegations and further interactions with EIP-7702 EOAs:

• wallet_getCapabilities (EIP-5792)
• wallet_sendTransaction

The sequencer also needs two additional configuration values, set via environment variables:

• One for the sequencer private key used for gas sponsoring (EXP0001_PK)
• One for the contract used for delegations in experiment 1 (EXP0001_ADDRESS)

For more context, see https://hackmd.io/@qCfD_jzVSzmS6lHmidSeRQ/HkhytUoCA
