add server side validation for mandatory param #130
Description
Currently in add alert/case apis we are not doing any validations. The mandatory checks are done from the client side (web portal).
- We need to add server side validation as well for mandatory params: so far messages/info in english is required.
- For the optional languages (si/ta) if the title is set, we must ensure the body is also present if not there will be incomplete info from user's pov
It's better to have a defined error response format as well (see - #131)
