[$80] Add Loading Indicator when the app is getting data from backend

[LieutenantRoger]

Current:

Currently, when we changed any filter, we will call the API to get the challenge data with latest updated Query

Expected:

When the API is trying to get the data from backend, we should display a loading indicator to let user is aware of that the API is loading data. This can happen when a user visits challenge page initially, or the user changed any filter that causing the reloading of the challenges data.

Please reuse the loading indicator we have implemented when loading a challenge detail page.
