Introduce `transactionConfig` to `Driver.executeQuery`

[bigmontz]

Transaction config enables the user to configure timeouts and set metadata for the transaction.

This configuration is already present in APIs such as Session.executeRead and Session.executeWrite.

Usage example:

const { records } = await driver.executeQuery(myQuery, myParams, {
    database: 'neo4j',
    transactionConfig: {
        timeout: 3000,
        metadata: { key: 'value' }
    }
})
