Optimize lib/instrumentation/core/http-outbound.js to only parse the URL once

[bizob2828]

Description

There's a lot of parsing happening in http-outbound.js around the URL. This was noticed while updating this code in #2169. We should parse the URL once and store it in some context to be referenced later. Aside from the url.parse which should get updated in #2209 any references to urltils.* should be optimized and leverage an already parsed URL.

Acceptance Criteria

Only parse the outgoing URL once to do any necessary operations in the lib/instrumentation/core/http-outbound.js.
