Replace console.log with structured logging

[LewisBroadhurst]

Closes #399

Winston logger has been used to replace the console.log() node logging in the git-proxy application. Logs generated from git-proxy use now have a format of [timestamp] [log level]: [log message], and can be found in the files git-proxy.log and error.log under the src/logging directory.

Before merging, I wanted to confirm that the old console.log() lines should be removed also. Maybe they are useful in some cases?

@LewisBroadhurst - thanks for the pull request - you're a star ⭐

In terms of keeping the old console.log calls, is there anything this would provide us that the usage of winston does not?

Looking good! 🍰

Can we think about whether we should use winston logging in log() in Step.js:

log(message) {
    const m = `${this.stepName} - ${message}`;
    this.logs.push(m);
    console.info(m);
}

Can we think about whether we should use winston logging in log() in Step.js:

log(message) {
    const m = `${this.stepName} - ${message}`;
    this.logs.push(m);
    console.info(m);
}

I think this is an example of keeping the console.log I mentioned initially, as having the values logged to console will be a much better UX? (and an npx installer wouldn't have log access?)

For this would the best solution be adding the winston logging in to the step, as well as keeping the console.log? Then we get the UX positives and logging.

Can remove the double logging from checkRepoInAuthorisedList.js with this too 😄

step.log(`repo ${action.repo} is not in the authorisedList, ending`);
- logger.info('setting error');

step.setError(`Rejecting repo ${action.repo} not in the authorisedList`);
- logger.error(`Rejecting repo ${action.repo} not in the authorisedList`);

+ log(message, isError = false) {
     const m = `${this.stepName} - ${message}`;
     this.logs.push(m);
+   if (!isError) {
+     console.info(m);
+     logger.info(m);
+   } else {
+     console.error(m);
+     logger.error(m);
+   }

Small suggestion on winston setup.
