Span Filter Option ignoreSpans

[thinkocapo]

Problem Statement

Hi, there's no way to filter out spans, like beforeSpan in javascript (which is getting deprecated in v9 JS SDK)

similar GH issue

• BeforeSend() for Spans #3245
• Add a way of ignoring/filtering child spans #1895

Solution Brainstorm

Sentry.init({
    ignorSpans: ['span_description']
})

or it could take a span attribute that represents multiple, like something for this span type that always says 'browser', maybe user wants to remove all spans that say browser.

or maybe user wants 1 http spans for a http request but not all the sub spans here like .proxy .dns etc.

regex would work nice
