Merge Judge0 DB into Common DB

[SujithThirumalaisamy]

Resolves: #5 Done it by adding the schema of judge0 into main database and optimise it further to make judge0 access the database without any issues and get rid of the callback.

• [x] Aggregate Database
• [x] Normalize Tables
• [x] Refactor Flow
• [x] Remove Callback service ( Wanted to be redundant) So Done...
• [x] Add the Contest logic to the Current flow

Can we do something like this tbh:

const testCases = problem.inputs.map((input, index) => ({
    submissionId: submission.id,
    judge0TrackingId: // this would be unque something like cuuid or uuid
    ...
}));

await db.testCase.createMany({ data: testCases });

const response = await axios.post(
    `${JUDGE0_URI}/submissions/batch?base64_encoded=false`,
    {
        submissions: testCases.map(testCase => ({
            language_id: LANGUAGE_MAPPING[submissionInput.data.languageId]?.judge0,
            source_code: problem.fullBoilerplateCode,
            stdin: testCase.input,
            expected_output: testCase.expected_output,
            callback_url: `${process.env.BASE_URL}/submission-callback/${testCase.judge0TrackingId}`,
        })),
    }
);
