hiveview: Client URL based filtering

[spencer-tb]

Adds a small change to filter all the simulations within index.html based on the client provided within the url.

For example, now /?client=go-ethereum will display only simulations by geth. This acknowledges that client names within simulation logs usually include extra metadata such as go-ethereum_cancun-git, hence the value specified in the url is matched against the string before the first _.

Client teams can now bookmark their specific simulations: https://hivecancun.ethdevops.io/?client=go-ethereum

I've implemented a more complete version of this in #864. Please try it. Main advantage of my thing is that you get a way of creating the URL by changing the select, whereas with this PR, you just sort of have to know that it can be filtered by URL.

However, my solution doesn't do the substring match.

Closing in favor of #864!
