Dashboard

# Description

The dashboard should present
- a summary of the data handled by Klaw (amounts of topics and requests
- a line chart showing the throughput of requests
- an analytics section breaking down that data per Cluster and per Team in bar charts

# Design


# Questions

- In Angular Klaw, all analytics are for the current user's team. However, in the design, the data we want to display seems to be different. Is it possible to get the following data from the existing API?
- for *all* teams:
- topics per team
- producers per team
- consumers per team
- possibly filtered by clusters
- for *all* clusters:
- topics per cluster
- producers per cluster
- consumers per cluster
- possibly filtered by team

- We need to ascertain that the `aquarium` chart components are usable in coral, and also be wary of the data format they will request (which will not fit what the API currently returns, for sure)
