Add Query String as URL Parameter

[ryandem1]

So filters on the enrich-ui need an easier way of being saved.

Here is an example query:

{
    "resolutions": ["Unresolved"],
    "docs": [
        {"owner": "Patrick Star"}
    ]
}

This gets base64 encoded and sent to the GET /tests endpoint to get a filtered set of tests.

In the UI, this process is performed in the filter modal:

As a UX improvement, it would be nice to have the filter that is applied to the test table to be dictated by a query URL parameter that is any base64 encoded query. This way, when a new filter gets applied to the test table, the URL will reflect the query.

This will make it easier to share, save, and modify test queries.
