Continue when a workload is not working

[rmahdav]

This PR fixes issue #82.

If a workload throws an error (during initialization or running), we show a warning on the result page and notify the user. I have tested the following situations:

1. A number of workloads throw error in each iteration. The list of them are shown on the result page and because they were not completed in any of the iterations, we exclude the measurement (in some cases is a few nano seconds because of the possible successful steps) from the result list and geomean calculation:

2. If a workload fails in some iterations, we show it as part of the failed workloads but include the successful iterations in results list and geomean calculation. Sentence similarity workloads failed for some random number of iterations in the below screenshot:

We can see the number of the iterations in the shown table for the workloads (sentence similarity on wasm, for example):

I also tested if the heights of the warning box is dynamic based on the number of the failed workloads and if it is not shown if all the workloads are successful.

This PR does have conflict with PR #114 , I'll wait for that one to merge and then rebase this one on top of that.
