Fetch remote collection URL at interval

[thim81]

Is your feature request related to a problem? Please describe.

We publish our Postman collection and Postman Environment file on a regular basis to a remote location, as part of a CI/CD flow. The postman-promotheus project would be used to monitor the API through the latest Postman changes.

Currently the Postman collection would only be loaded on StartUp of the express webserver =>

postman-prometheus/src/server.js

Line 108 in ece229c

app.listen(port, async () => {

This would mean that after each change, we would have to restart the "postman-promotheus" application to get the latest changes.

Describe the solution you'd like

To facilitate automation, it would perhaps be interesting to also "reloaded" the remote fetching of the collection URL at a certain interval or after x runs?

Describe alternatives you've considered

We could figure out a way to restart the postman-promotheus application, every time a new Postman collection is made available, but that would mean linking them both more closely together, which is less desired.

Additional context
The same would apply for a potential new feature request (#5)
