Update to use M2M token for Topcoder-X

[jmgasper]

Current

Currently, when using the Challenge API, we have to:

• Login with a service account
• Upgrade the token to a v3 token

Only after that can we use the API.

Problem

The problem with that flow is that Auth0, the login provider, rate limits us, so we've been having issues where things aren't getting handled in Topcoder-X because the login flow is failing.

Solution

Topcoder APIs now support M2M tokens, so we are going to strip out the service account support and move to M2M tokens instead.

The latest release can be found here:

https://github.com/appirio-tech/tc-core-library-js/releases/tag/v2.4

This isn't in NPM yet, so we'll have to update this as a git ref in the package.json.

Example

Example usage for token generation can be seen in the v5 sub api here

Hi @jmgasper,

Can we find any document that helps us to get or generate the AUTH0_CLIENT_ID and AUTH0_CLIENT_SECRET?

I've learned how to use the M2M tokens and it needs AUTH0_CLIENT_ID and AUTH0_CLIENT_SECRET.
