The dashboard needs to poll data at a set frequency

[gabecoelho]

Describe feature request.
The dashboard needs to poll data from the backend at a set frequency in order to show the most up-to-date data (i.e. every 5s).

Describe the solution
The dashboard should display the most up-to-date information about claims files installed either locally or Porter claims saved in the cloud. This polling should not break the dashboard if for some reason

Describe alternatives you've considered
An idea we have considered is implementing sockets. We have decided not to do it for this iteration of the project given the client-server architecture.
