WalletType: mutation - configureWallet

type SimpleWalletConfig {
  onchainAddress: String!
}
type AdvancedWalletConfig {
  macaroon: String!,
  host: String!
}
mutation {
  configureWallet(
    simpleConfig: SimpleWalletConfig,
    advancedConfig: AdvancedWalletConfig,
    federatedConfig: Boolean
  )
}

• Fail if more than 1 config option is provided in a single request: "Please provide only 1 of simpleConfig, advancedConfig, or federatedConfig"
• Fail if federatedConfig is provided, but the Contributor does not have any Allocations for Projects linked to a Wallet with a voltage_api_key
• If the user already has a Wallet record, simply update it with whatever new config is provided
• If the federatedConfig is provided, check for a voltage_api_key on the Contirbutor's Allocations for Projects linked to a Wallet
  • If api keys are found, use them to hit the Voltage API: https://api-docs.voltage.cloud/#tag/Node/paths/~1node~1create/post
