Improve design of info bar at top of dashboards

[siddharth-krishna]

We got some feedback that this top bar was confusing to some users. Heba has some ideas for how to improve it.

While we are at it, we should also think about how to present this information when we have

• more than one machine type, and
• more than one timeout value

For example, in the next benchmark run, we plan to run the R sized benchmarks on a larger machine with a larger 10h timeout. The existing benchmarks will be run on the existing machine with a 1h timeout.

Perhaps one idea is to have tabs on the top of the dashboard so that the user can select between smaller benchmarks and real-sized benchmarks. This will also simplify the SGM calculation, as each "tab" will use a single TO/ER value for runtime.
