Introduce `auth` config to `Driver.executeQuery`

[bigmontz]

The AuthToken will be used for executing the query.

By default, the query executor will use connections authenticated with the AuthToken configured on driver creation. This new configuration allows switching user and/or authorization information for the underlying transaction's lifetime.

Example:

const { records } = await driver.executeQuery('RETURN $abc', { abc: 'dfe' }, {
   database: 'neo4j',
   auth: neo4j.auth.basic('otheruser', 'sup3rDup3rS3cret')
})

[!NOTE] This option is only available when the driver is connected to Neo4j Database servers which supports Bolt 5.1 or newer.
