Test creation Validation

[JadeMaveric]

Describe the bug
There are multiple validation failures while creating tests.

• The test can be give negative marks
• Duration can be negative (rolls over when processed by backend)
• Answer provided in MCQ questions doesn't need to be one of the options (see bitfield in Multiple Select and Numerical Answer Type Questions + (Dynamic #choices) #82 for a solution)
• Number of questions can be negative
• Total marks and number of questions required in the generated test aren't validated with the number of questions in the question bank

To Reproduce
Steps to reproduce the behavior:

1. Create a new test

2. Give it negative marks (-100)

3. Give it negative duration (0 hours, -20 mins) (-ve hours gives a warning)
   

4. Add question, all 4 options need to be selected
   

5. Add negative no. of questions and negative marks
   

6. Press next after verifying
   

7. Check the dashboard (local build on latest master branch)
   

Expected behavior
Error message should be shown whenever a validation fails. And the next button blocked until the mistakes are corrected.

Hi, the validations are being performed on the client side only and not on the server side. So, if instead of creating the test using the UI I send a post request to the server with marks as negative, the test will be created. Therefore, validations need to be performed server side as well and in case the validations fail, the user should be redirected accordingly
