scheduleTwinUpdate throws an error if "maxExecutionTimeInSeconds" isn't set even if it's marked as optional

[Apokalypt]

Problem encounter

The "maxExecutionTimeInSeconds" property is marked as optional in your typing file, but it isn't really. In fact, depending on the parameters passed, you may or may not set a default value. The problem is that the Microsoft API expects a value, and so, when you don't set a default value, the API throws an error...

What should happen ?

In ALL cases, when the property "maxExecutionTimeInSeconds" isn't set, you should set the default one OR never set it but ask the developer to set a value

Code to reproduce

const { JobClient } = require('azure-iothub')

const jobClient = JobClient.fromConnectionString(process.env['IotHubConnectionString'])

setImmediate( async () => {
        const id = 'aRandomId'
        await jobClient.scheduleTwinUpdate(
            id,
            "tags.model = 'test' AND deviceId IN ['aValidDeviceId']",
            {
                etag: '*',
                tags: { model: 'test', firmwareGroup: 'test-group-A' },
                properties: {
                    desired: {
                        firmware: 'aValue'
                    }
                }
            },
            new Date()
        )
})
