Ember service to observe when a request is in progress

Current version is running ember-cli >= 3.1.0

ember install ember-request-observer

Inject the service to controller or component

requestObserver: inject.service('request-observer')

Use the requestInProgress method like so: requestObserver.requestInProgress

It can be used on the controller/component as well as in the template like so:

{{requestObserver.requestInProgress}}

All contributions are welcomed and encouraged.

Please make all pull requests to the dev branch.

Thanks!
