New-AzApiManagementCertificate needs to allow Certificate without Password

[solankisamir]

Description of the new feature

The API does not require Password as a mandatory property when uploading. But the Cmdlet enforces the property.

Proposed implementation details (optional)

Please make Password as Optional

Thanks for the feedback! We are routing this to the appropriate team for follow-up. cc @miaojiang.

@dingmeng-xue or @solankisamir - is this issue still present in the latest version 4.0.2?
