[azure sql database] Fail to call azure rest api to get azure sql resources when resources has special characters, e.g., '/' and '%'

When I am trying out this API

- when my azure sql schema contains special character '/', it will report
{"error":{"code":"ResourceNotFound","message":"The specified resource '***' was not found."}};
- when my azure sql schema contains special character '%', it will report
{
"error": {
"code": "InvalidDoubleEncodedRequestUri",
"message": "The request URI '**/schemas/testpercent%25schema/tables?api-version=2021-02-01-preview' is not valid, because it contains double encoding sequence '%25'."
}
}

Start with the Azure SQL REST API request and error examples in this issue, focusing on the schema and table resource path. Trace how schema names containing '/' and '%' are represented in the API specification, and consider the work done when both resource forms can be requested without ResourceNotFound or double-encoding errors.
